i want to make multi level dropdown menu using select and option method
<select>
<option value="" data-display-text="Select">None</option>
<option value="oranges">SSC</option>
<option value="oranges">GATE</option>
<option value="bananas">BANK PO</option>
<option value="bananas">RAILWAY</option>
</select>
As far as I understand from your "multi level dropdown" concept, you can make a simple dropdown and just move some elements with CSS. Category name is stored in optgroup.
<select name="select_projects" id="select_projects">
<option value="">project.xml</option>
<optgroup label="client1">
<option value="">project2.xml</option>
</optgroup>
<optgroup label="client2">
<option value="">project5.xml</option>
<option value="">project6.xml</option>
<optgroup label="client2_a">
<option value="" style="margin-left:23px;">project7.xml</option>
<option value="" style="margin-left:23px;">project8.xml</option>
</optgroup>
<option value="">project3.xml</option>
<option value="">project4.xml</option>
</optgroup>
<option value="">project0.xml</option>
<option value="">project1.xml</option>
</select>
Update:
Or if you are trying to make a "chain" of dropdowns like you have in start menu in Windows, that is the easiest way to do it:
https://jqueryui.com/menu/
You can't make multiple levels with the select element.
In this case you would create a custom component with the capability to display something like 'hierarchic'.
Or use the trick like this:
<select>
<option>select me</option>
<option> me indented</option>
<option> even more indentation</option>
</select>
If you want to use ONE select you could use <optgroup/>. See example.
Note: it's not very multi-level, but it allows for some kind of relevant grouping.
<select>
<option value="" selected="selected">Select an option...</option>
<optgroup label="SSC">
<option value="oranges1">some option</option>
<option value="oranges2">some option</option>
<option value="oranges3">some option</option>
</optgroup>
<optgroup label="GATE">
<option value="bananas1">some option</option>
<option value="bananas2">some option</option>
<option value="bananas3">some option</option>
</optgroup>
<optgroup label="BANK PO">
<option value="apples1">some option</option>
<option value="apples2">some option</option>
<option value="apples3">some option</option>
</optgroup>
<optgroup label="RAILWAY">
<option value="grapes1">some option</option>
<option value="grapes2">some option</option>
<option value="grapes3">some option</option>
</optgroup>
</select>
You can't make multiple levels with the select element.
Any ways, if its any help, there's
<select>
<optgroup label="Swedish Cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
</optgroup>
<optgroup label="German Cars">
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</optgroup>
</select>
Maybe this can insprire you even if not totally correctly interpreted by editors.
<div class="col-2 search-filter">
<select id="searchByYear" multiple="multiple" ng-model="varYear.value">
<option value="2023">2023

I am currently trying to make a simple web application which logs to the console the values that are selected in an HTML drop-down menu. However, whenever I change my options in a different select, it ends up showing a value in the #player select. For example, if I chose Shot on Cage and clicked save, the console would show that the value to be b. If I am not explaining this thoroughly enough, please let me know, and I will try to re-explain my difficulties.
function myFunction() {
var a = document.getElementById("player").selectedIndex;
console.log(document.getElementsByTagName("option")[a].value);
var b = document.getElementById("what").selectedIndex;
console.log(document.getElementsByTagName("option")[b].value);
var c = document.getElementById("where").selectedIndex;
console.log(document.getElementsByTagName("option")[c].value);
var d = document.getElementById("when").selectedIndex;
console.log(document.getElementsByTagName("option")[d].value);
}
<select id="player">
<option value="b">B</option>
<option value="n">N</option>
<option value="a">A</option>
<option value="c">C</option>
<option value="m">M</option>
<option value="j">J</option>
<option value="ja">Ja</option>
</select>
<select id="what">
<option value="shoton">Shot on Cage</option>
<option value="shotoff">Shot off Cage</option>
<option value="goal">Goal</option>
<option value="assist">Assist</option>
<option value="block">Block</option>
<option value="steal">Steal</option>
<option value="turnover">Turnover</option>

</select>
<select id="where">
<option value="set">Set</option>
<option value="navy">Navy</option>
<option value="leftwing">1/2 side past 5</option>
<option value="rightwing">4/5 side past 5</option>

<button type="button" onclick="myFunction()"> Save </button>
This will work for you.
.getElementsByTagName("option") will ruin your result as it will select all the <option> tags and it post the result as one.
So try this code it will work.
function myFunction() {
var a = document.getElementById("player");
console.log(a.options[a.selectedIndex].value);
var b = document.getElementById("what");
console.log(b.options[b.selectedIndex].value);
var c = document.getElementById("where");
console.log(c.options[c.selectedIndex].value);
var d = document.getElementById("when");
console.log(d.options[d.selectedIndex].value);
}
<select id="player">
<option value="b">B</option>
<option value="n">N</option>
<option value="a">A</option>
<option value="c">C</option>
<option value="m">M</option>
<option value="j">J</option>
<option value="ja">Ja</option>
</select>
<select id="what">
<option value="shoton">Shot on Cage</option>
<option value="shotoff">Shot off Cage</option>
<option value="goal">Goal</option>
<option value="assist">Assist</option>
<option value="block">Block</option>
<option value="steal">Steal</option>
<option value="turnover">Turnover</option>
<option value="drawn">Ejection Drawn</option>
<option value="ejected">Ejected</option>
</select>
<select id="where">
<option value="set">Set</option>
<option value="navy">Navy</option>
<option value="leftwing">1/2 side past 5</option>
<option value="rightwing">4/5 side past 5</option>
<option value="point">Point/3</option>
<option value="lefttwo">1/2 side 2 meter</option>
<option value="righttwo">4/5 side 2 meter</option>
<option value="1">6 on 5 1</option>
<option value="2">6 on 5 2</option>
<option value="3">6 on 5 3</option>
<option value="4">6 on 5 4</option>
<option value="5">6 on 5 5</option>
<option value="6">6 on 5 6</option>
</select>
<select id="when">
<option value="q1">Quarter 1</option>
<option value="q2">Quarter 2</option>
<option value="q3">Quarter 3</option>
<option value="q4">Quarter 4</option>
</select>
<button type="button" onclick="myFunction()"> Save </button>
options[a.selectedIndex].value this simple will get you the value of the selected option value in the select and in javascript option in a property of select which we can combain with selectedIndex property and get you value.
Hope this was helpfull.
you have many options split into 4 selects ... document.getElementsByTagName will receive them ALL ... so using the selectedIndex is only valid for the fist select
you can use getElementsByTagName on any element - so, in this case you would use it on the select element
function myFunction() {
var a = document.getElementById("player");
console.log(a.getElementsByTagName("option")[a.selectedIndex].value);
var b = document.getElementById("what");
console.log(b.getElementsByTagName("option")[b.selectedIndex].value);
var c = document.getElementById("where");
console.log(c.getElementsByTagName("option")[c.selectedIndex].value);
var d = document.getElementById("when");
console.log(d.getElementsByTagName("option")[d.selectedIndex].value);
}
<select id="player">
<option value="b">B</option>
<option value="n">N</option>
<option value="a">A</option>
<option value="c">C</option>
<option value="m">M</option>
<option value="j">J</option>
<option value="ja">Ja</option>
</select>

<option value="shoton">Shot on Cage</option>
<option value="shotoff">Shot off Cage</option>
<option value="goal">Goal</option>

<select id="where">
<option value="set">Set</option>
<option value="navy">Navy</option>
<option value="leftwing">1/2 side past 5</option>
<option value="rightwing">4/5 side past 5</option>
<option value="point">Point/3</option>
<option value="lefttwo">1/2 side 2 meter</option>
<option value="righttwo">4/5 side 2 meter</option>
<option value="1">6 on 5 1</option>
<option value="2">6 on 5 2</option>
<option value="3">6 on 5 3</option>
<option value="4">6 on 5 4</option>
<option value="5">6 on 5 5</option>

<option value="q3">Quarter 3</option>
<option value="q4">Quarter 4</option>
</select>
<button type="button" onclick="myFunction()"> Save </button>
That being said, this still isn't the best solution - use #weBBer's code INSTEAD
because a <select> element has a property called options, which you can use the selectedIndex property to get the selected <option> - see the better answer for an example

I need make two level select option with javascript or jquery I don't know how JavaScript works and I need help.
You can do it like this:
$('#subcategory').find('optgroup').hide(); // initialize
$('#category').change(function() {
var $cat = $(this).find('option:selected');
var $subCat = $('#subcategory').find('.' + $cat.attr('class'));
$('#subcategory').find('optgroup').not("'" + '.' + $cat.attr('class') + "'").hide(); // hide other optgroup
$subCat.show();
$subCat.find('option').first().attr('selected', 'selected');
});

Two Level selectoption AKA Multilevel dropdowns can designed using HTML,CSS.
Based on the functional requirements, Javascript can be used for implementing additional features in Multilevel dropdowns.
Multilevel dropdowns can be designed by making use of <div> tags or <ul> tags .
i Personally prefer <ul> tags
Take a look at my codepen (https://codepen.io/Divine1/pen/mXVPmQ) to have an understanding on how to start designing multi-level dropdown.
Check it out:
var el = document.getElementById('category');
el.onchange = function(){
var category = $('#category :selected').attr('class');
$('#subcategory optgroup').hide();
$('#subcategory').val("");
$('#subcategory .'+category).show();
}
#subcategory optgroup{
display:none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="category" required>
<option value="">select model type</option>
<option class="Volvo" value="1">Volvo</option>
<option class="Saab" value="2">Saab</option>
<option class="Opel" value="3">Opel</option>
<option class="Audi" value="4">Audi</option>
</select>
<select id="subcategory">
<optgroup class="Volvo" required>
<option value="">select model type</option>
<option value="44">XC60</option>
<option value="55">XC90</option>
</optgroup>
<optgroup class="Saab" required>
<option value="">select model type</option>
<option value="66">Saab 9XX</option>
<option value="77">Saab Aero-X</option>
</optgroup>
<optgroup class="Opel" required>
<option value="">select model type</option>
<option value="88">Corsa A</option>
<option value="99">Corsa B</option>
</optgroup>
<optgroup class="Audi" required>
<option value="">select model type</option>
<option value="616">Audi A4</option>
<option value="717">Audi A8</option>
</optgroup>
</select>
I want to delete the first option of the selected and I have selected tag id and class but the problem is selected class and id is changing when I open the form of different-2 event.and class "r" of selected tag is using more than one time different-3 drop down of form.
I want to remove the selected option using title attribute of selected tag.
If any other way to resolved this type of problem please share.
<select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="State*">
<option value="">Select One </option>
<option value="Michigan"> Michigan</option>
<option value="Alabama"> Alabama</option>
<option value="Alaska"> Alaska</option>
<option value="Arizona"> Arizona</option>
<option value="Arkansas"> Arkansas</option>
<option value="California"> California</option>
<option value="Colorado"> Colorado</option>
<option value="Connecticut"> Connecticut</option>
<option value="Delaware"> Delaware</option>
<option value="Florida"> Florida</option>
<option value="Georgia"> Georgia</option>
</select>
I want to delete
<option value="">Select One </option>
Here is how to select using class and title in plain JavaScript
window.onload=function() {
var sel = document.querySelector("select.r[title='State*']");
console.log(sel);
sel.options[0]=null;
}
<select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="State*">
<option>Please select State</option>
<option>option 1</option>
</select>
<select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="NotState*">
<option>Please select Not State</option>
<option>option 1</option>
</select>
Ditto in jQuery
$(function() {
var $options = $("select.r[title='State*'] option");
$options.eq(0).remove();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="State*">
<option>Please select State</option>
<option>option 1</option>
</select>
<select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="NotState*">
<option>Please select Not State</option>
<option>option 1</option>
</select>
you can add the hidden attribute:
<option value="" hidden>Select One</option>
this will result in being the default selected value but you can't select it in the dropdown
Example:
<select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="State*">
<option value="" hidden>Select One</option>
<option value="Michigan">Michigan</option>
<option value="Alabama">Alabama</option>
<option value="Alaska">Alaska</option>
<option value="Arizona">Arizona</option>
<option value="Arkansas">Arkansas</option>
<option value="California">California</option>
<option value="Colorado">Colorado</option>
<option value="Connecticut">Connecticut</option>
<option value="Delaware">Delaware</option>
<option value="Florida">Florida</option>
<option value="Georgia">Georgia</option>
</select>
The hidden attribute can also be used to keep a user from seeing an element until some other condition has been met (like selecting a checkbox, etc.).
The hidden attribute is new in HTML5.

In your scenario if select box's id is changing dynamically then you can achieve this with it's class name like below
$(".r option[value='']").each(function() {
$(this).remove();
});
If you want to delete it by using ID then you can do it like this..
$("#DROPDOWN_735 option[value='']").each(function() {
$(this).remove();
});
Or
$("select option[value='']").each(function() {
$(this).remove();
});
Try this
$(document).ready(function() {
$("select[title='State*'] option:first-child[value='']").remove();
})
<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.1.1.min.js"></script>
<select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="State*">
<option value="">Select One </option>
<option value="Michigan"> Michigan</option>
<option value="Alabama"> Alabama</option>
<option value="Alaska"> Alaska</option>
<option value="Arizona"> Arizona</option>
<option value="Arkansas"> Arkansas</option>
<option value="California"> California</option>
<option value="Colorado"> Colorado</option>
<option value="Connecticut"> Connecticut</option>
<option value="Delaware"> Delaware</option>
<option value="Florida"> Florida</option>
<option value="Georgia"> Georgia</option>
</select>
<select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="State*">
<option value="">Select One </option>
<option value="Michigan"> Michigan</option>
<option value="Alabama"> Alabama</option>

Hope it will be useful.
I have two HTML drop down
<select>
<option value="">Please Select</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
<select>
<option value="">Please Select</option>
<option value="a">a</option>
<option value="b">b</option>
</select>
Now, If I Select volvo from first drop down and b from second dropdown and then I change to Audi in the first dropdown, I want the value of second drop down to show Please Select instead of b (selected previously) using javascript
PS: I am new to Javascript
It's as easy as:
<select onChange="document.getElementById('secondOption').selectedIndex = 0;">
<option value="">Please Select</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
<select id="secondOption">
<option value="">Please Select</option>
<option value="a">a</option>
<option value="b">b</option>
</select>
You can reset the index supposing you've two <select>
var selects = document.getElementsByTagName('select');
selects[0].onchange = function(){
selects[1].selectedIndex = 0;
}
i have many dropdowns in my page.
for dropdowns i am using select2 plugin.
i don't want to use select2 plugin for some of the dropdowns.
is there any way to do so?
i have searched on google and also have gone through their documentation but i didn't get anything related this.
this is my select box code ..
<div class="cust-input">
<select name="management[]">
<option value="0">Select Management</option>
<option value="Chairman">Chairman</option>
<option value="Vice Chairman">Vice Chairman</option>
<option value="Vice Chancellor">Vice Chancellor</option>
<option value="Secretary">Secretary</option>
<option value="Registrar">Registrar</option>
<option value="Dean">Dean</option>
<option value="Owner">Owner</option>
<option value="Other">Other</option>
</select>
</div>
You can implement that using specific class instead of common select tag element.
use:
$(".useSelect2").select2(); //either your desired name of your class or unique ID
instead of
$("select").select2(); // if you used this method, select2 will applied to all dropdowns.
Example:
<select name="management[]" class="useSelect2">
<option value="0">Select Management</option>
<option value="Chairman">Chairman</option>
<option value="Vice Chairman">Vice Chairman</option>
<option value="Vice Chancellor">Vice Chancellor</option>
<option value="Secretary">Secretary</option>
<option value="Registrar">Registrar</option>
<option value="Dean">Dean</option>
<option value="Owner">Owner</option>
<option value="Other">Other</option>
</select>
Javascript:
$(".useSelect2").select2();
Other dropdowns:
<select name="management[]" class="dontuseSelect2">
<option value="0">Select Management</option>
<option value="Chairman">Chairman</option>
<option value="Vice Chairman">Vice Chairman</option>
<option value="Vice Chancellor">Vice Chancellor</option>
<option value="Secretary">Secretary</option>
<option value="Registrar">Registrar</option>
<option value="Dean">Dean</option>
<option value="Owner">Owner</option>
<option value="Other">Other</option>
</select>
Put a class on the select elements you want to use select2 with, and then use that class to instantiate the plugin. Something like this:
$('.select2').select2();
<div class="cust-input">
<select name="management[]" class="select2">
<option value="0">Select Management</option>
<option value="Chairman">Chairman</option>
<option value="Vice Chairman">Vice Chairman</option>
<option value="Vice Chancellor">Vice Chancellor</option>
<option value="Secretary">Secretary</option>
<option value="Registrar">Registrar</option>
<option value="Dean">Dean</option>
<option value="Owner">Owner</option>
<option value="Other">Other</option>
</select>
<!-- this select will not be styled -->
<select>
<option>Foo</option>
<option>Bar</option>
</select>
