Create a dynamic submenu in dropdown

I have reasons for rescheduling job and also sub-reason under a reason. I want that on selecting the reason, its sub-reason should appear. How do I do that?
<select>
<option value="" disabled="disable" selected="selected">
Select Reason
</option>
<option ng-repeat="reasons in Resonse_schedule ">
{{reasons.reasons}}
</option>
</select>

Use ng-options
AngularJS provides a directive ng-options to dynamically list down the options
<select ng-options="reason.reason as reason.reason for reason in Resonse_schedule">
<option value="" selected disabled >Select Reason</option>
</select>
I would suggest you to go through the documentation of ngOptions to understand it better

You can use this:
<select ng-model="reasonVar" ng-options="reason as reason.name for reason in Resonse_schedule">
<option value="" disabled="disable" selected="selected">Select Reason
</option>
</select>
<select ng-model="reasonSelected">
<option ng-repeat="subReason in reasonVar.subReasons" value="subReason.name">
{{subReason.name}}
</option>
</select>
Where reasonVar is the selected value from the Resonse_schedule list.

Toggling ng-selected

I am trying to toggle ng-selected options in Angular, but am running into some difficulty. Here's what I'm trying:
<select ng-model="datacut.ages" multiple>
<option value="" disabled="disabled">Please Select</option>
<option value="0-15" ng-click="toggleSelect(datacut, '0-15')" ng-selected="datacut.ages.indexOf('0-15') !== -1">15 and Younger</option>
<option value="16-19" ng-selected="datacut.ages.indexOf('16-19') !== -1">16 - 19</option>
<option value="20-24" ng-selected="datacut.ages.indexOf('20-24') !== -1">20 - 24</option>
</select>
Controller:
$scope.toggleSelect = function(dc, str){
dc.ages.splice(dc.ages.indexOf(str), 1);
//e.currentTarget.selected = !e.currentTarget.selected;
};
The problem is that when I click on an option gets selected on mousedown, and on release gets unselected. The commented out code also does the same thing.
I feel like this should have a simple solution, but I can't really figure out an elegant solution.
Any help would be much appreciated.
Edit: For clarification - I need to be able to have nothing selected, so clicking a single selected element needs to unselect it. I also need to be able to select multiple options.

Your are using ng-model which does the magic for you. So ng-click and ng-selected is not necessary. See my working fiddle
<select ng-model="datacut.ages" multiple>
<option value="" disabled="disabled">Please Select</option>
<option ng-value="'0-15'">15 and Younger</option>
<option ng-value="'16-19'" >16 - 19</option>
<option ng-value="'20-24'" >20 - 24</option>
</select>

It looks like you want to remove the selected age from the ages model. Then you need to use the ng-change directive. And remove the ng-click or ng-selected. But leave the ng-model to access the value on the method that remove the selected item.
See my plunker
<select multiple name="ages" unseletable forbiden-opt="datacut.MIN_AGE" ng-model="datacut.chosenAge">
<option value="" disabled="disabled">Please Select</option>
<option ng-repeat="age in datacut.ages" value="{{age}}">
{{age}}
</option>
</select>
EDIT: This should be made in a directive because you need to update the option html to unselect the option.

Prevent Blank Select in Angular

I updating a form to angular. The selects in it are not generated by angular. I am using angular to add some interactivity and submit the form. I am having an issue where angular is adding a blank select to the element. Is there a way of preventing this without having angular generate the select?
<select name="inventory_status" ng-model="formData.inventory_status">
<option ng-selected="true" ng-value="1">Active</option>
<option ng-value="2">Discontinued</option>
<option ng-value="3">Special Order</option>
<option ng-value="4">Pre-Order</option>
</select>
The above code produces this:
<select name="inventory_status" ng-model="formData.inventory_status" ng-init="sortorder='1'" class="ng-pristine ng-valid ng-touched"><option value="? undefined:undefined ?"></option>
<option ng-selected="true" ng-value="1" value="1" selected="selected">Active</option>
<option ng-value="2" value="2">Discontinued</option>
<option ng-value="3" value="3">Special Order</option>
<option ng-value="4" value="4">Pre-Order</option>
</select>
My hope is to not have this produced:
<option value="? undefined:undefined ?"></option>
Additionally I would like to not have to use angular to generate the dropdown although if that is the only option I could. This only happens when I set this field to ng-model. I am setting it to ng-model because I want to use angular to submit the form.
Thanks in advance.

Set $scope.formData.inventory_status = 1 or whatever value you want selected and it will not show the empty option, plus you don't need ng-selected if you set the value.

AngularJS - Changing text of default option inside ngOptions

I have a select menu using ng-options to repeat the options, and I have a default <option> inside the menu:
<select ng-model="selected" ng-options="d.id as d.value for d in data">
<option value="">Choose an option</option>
</select>
Problem: I want to make it so that the text inside that default option changes based off another property in the $scope, and I tried the following and it doesn't work:
<select ng-model="selected" ng-options="d.id as d.value for d in data">
<option value="" ng-if="!optional">Choose an option</option>
<option value="" ng-if="optional">Choose an option (optional)</option>
</select>
It seems it will only show one default <option> element, so I also tried the following with ng-show but it doesn't work either:
<select ng-model="selected" ng-options="d.id as d.value for d in data">
<option value="">Choose an option <span ng-show="optional">(optional)</span></option>
</select>
I know you can also do <option ng-repeat> inside the select menu, but the data for the options comes from an AJAX call and doesn't update correctly when the data first comes in, so I'm sticking to using <select ng-options>.
Here's a JSFiddle with the problem.
Any suggestions for how I could go about getting this to work?

Your first try didn't work because, as said by the documentation of select in AngularJS, only "a single hard-coded <option> element can be nested into the <select> element".
Your second try didn't work because the <option> element can only receive "text (with eventually escaped characters like é)" as content, and not any tag like the <span> you've tried.
The solution is simply to use interpolation:
<select ng-model="selected" ng-options="d.id as d.value for d in data">
<option value="">Choose an option {{optional ? '(optional)' : ''}}</option>
</select>

Have you tried setting the text with template markup?
<select ng-model="selected" ng-options="d.id as d.value for d in data">
<option value="">{{defaultOptionText}}</option>
</select>

AngularJS - extra blank option added using ng-repeat in select tag

I have a listbox that I am creating with a select, using AngularJS ng-repeat. The listbox is created correctly, and when I select one of the items and click my button, I get to the function and have the information I need.
My html code is as follows:
<select size="6" ng-model="item" ng-options="s.name for s in itemlist"></select>
<button class="btn tt-btn-blue" ng-model="singleModel" ng-click="onLoadClicked(item.id)">Load</button>
My problem is that when the listbox paints, it has one item at the top that is blank. When I inspect the listbox during a run in Chrome, I get the following output in the console:
<select size="6" ng-model="item" ng-options="s.name for s in itemlist" class="ng-pristine ng-valid">
<option value="?" selected="selected"></option>
<option value="0">Item 1</option>
<option value="1">Item 2</option>
<option value="2">Item 3</option>
<option value="3">Item 4</option>
<option value="4">Item 5</option>
<option value="5">Item 6</option>
</select>
I am wondering how I can get rid of the first option inserted by the ng-repeat. I don't want to see a blank space at the top of the listbox. I realize one option would be to set the first actual option (value="0") as the selected item, but I would rather have no selected items to start.

Any time you see <option value="?" selected="selected"></option> in the select, it means that your ng-model is set to a value that isn't in the ng-options. So, if you don't want the blank option, you need to make sure item is set to a value in your itemlist. This could be as easy as having the following in your controller:
$scope.item = $scope.itemlist[0];
This will give it an inital value, and then angular will update it for you thereafter.

simplest way to make sure that automatically added option by angular is hidden is ng-if directive.
<select ng-options="option.id as option.description for option in Options">
<option value="" ng-if="false"></option>
</select>

I have found the solution after a long RND
Please find the following code it will work for you.
Here is the HTML Code
<div class="col-xs-3" ng-controller="GetUserADDetails">
<label>Region</label>
<select id="DDLRegion" ng-model="selectedregion" class="form-control" ng-change="getBranched(selectedregion)">
<option value="" >--Select Region--</option>
<option ng-repeat="region in Regions" value="{{region.LookupID}}">{{region.LookupValue}}</option>
</select>
</div>
Here is the Module Code
var app = angular.module("UserMasterModel", [])
.controller("GetUserADDetails", function ($scope, $http,$log) {
$http({
method: 'GET',
url: '/UserMaster/GetAllRegion'
})
.then(function (response) {
$scope.Regions = response.data;
//$log.info(response);
});
});
