On my page using Internet explorer I have a drop down but on the first load of the page because it has a onFocus on it, it needs a double click to show menu. How do I avoid the double click.
The onFocus must still fire but the menu must show at the same time?
how do I do this because the double click is irritating?
Here is a simple example
http://jsfiddle.net/tgH7b/3/
here is the code
<select name="cars" >
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="fiat" selected="selected">Fiat</option>
<option value="audi">Audi</option>
</select>
<select name="cars" onFocus="this.style.background = '#999';$(this).click();">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="fiat" selected="selected">Fiat</option>
<option value="audi">Audi</option>
</select>
The only solution i can think of is to use focusin() callback function instead:
NOTE: focusin() supports event bubbling
http://jsfiddle.net/2AUs6/
<select name="cars" >
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="fiat" selected="selected">Fiat</option>
<option value="audi">Audi</option>
</select>
<!-- this one -->
<select name="cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="fiat" selected="selected">Fiat</option>
<option value="audi">Audi</option>
</select>
$('select[name=cars]:eq(1)').focusin(function(){
$(this).css('background','#999')
})
Here is a possible solution from code project

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
<option value="2023-H1">H1</option>
<option value="2023-H2">H2</option>
</option>
<option value="2022">2022
<option value="2022-H1">H1</option>
<option value="2022-H2">H2</option>
</option>
<option value="2021">2021
<option value="2021-H1">H1</option>
<option value="2021-H2">H2</option>
</option>
<option value="2020">2020
<option value="2020-H1">H1</option>
<option value="2020-H2">H2</option>
</option>
<option value="2019">2019
<option value="2019-H1" >H1</option>
<option value="2019-H2" >H2</option>

</select>

My question is how can I display more than one drop downs on same page for same functionality in C#. Let's say I have 3 panels on a page, I want to show a drop down in all three panels but changing the value of one drop down will cause changing the values of others too.
I can't use id access in JS because if there are 3 drop downs on same page of same ID i.e ID is not unique then Java Script can't perform actions.
Just apply same class to all dropdowns and on change of any of dropdown set that value to all dropdowns please find snippet below.
$(".selectclass").on("change",function(){
$(".selectclass").val($(this).val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select class="selectclass">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
<select class="selectclass">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
<select class="selectclass">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
You can assign different Class all three dropdown and call change event
<select id="ddlUnquie" class="one" >
<option value="firstvalue">first dropdown text</option>
<option value="firstsecond">first second text</option>
</select>
<br>
<br>
<select id="ddlUnquie" class="two" >
<option value="firstvalue">first dropdown text</option>
<option value="firstsecond">first second text</option>
</select>
<br>
<br>
<select id="ddlUnquie" class="three" >
<option value="firstvalue">first dropdown text</option>
<option value="firstsecond">first second text</option>
</select>
Below is Jquery code
$(".one").change(function()
{
alert($(this).val());
})
$(".two").change(function()
{
alert($(this).val());
})
$(".three").change(function()
{
alert($(this).val());
})
Also you can use jsfillde link https://jsfiddle.net/1xzkmbtk/
I created a drop down as
<body>
<div style="height:200px"></div>
<form id="myForm">
<select style="margin-left:200px">
<option value="">Select a vehicle</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>
</form>
</body>
which appears in Internet explorer as normal. That is on click, the dropdown flips down. But if we resize the browser window and click the dropdown, it flips up with the list starting from the top. Is there any css solution for making the dropdown always flips down. Or can we make it using javascript or jquery? And this problem is only with the Internet Explorer.
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>
