I am trying to show tags in a Bootstrap select combobox. However, ng-repeat is not populating the options. After some research, I believe I need to write a directive for this, because Bootstrap takes the options and makes a list out of them before Angular adds the options. But I don't know what writing a directive involves.
<select class="combobox form-control" ng-model = "tags.repeatSelect">
<option ng-repeat = "tag in tags.tagNames" value = "{{tag.string}}"> {{tag.string}} </option>
This may solve your problem.
<select data-ng-model="modelValue" class="form-control" data-ng-options="item.string for item in tags.tagNames">
</select>

I want to bind a model value to selected item
<select id="hours" ng-model="v.T_Hour">
<option ng-repeat="n in [].constructor(24) track by $index" ng-selected="{{$index==v.T_Hour}}" value="{{$index}}">{{$index>9?$index:"0"+$index}}:00</option>
</select>
I want after the page loads , the value of the model 'v.T_Hour' to be selected in select , i assign the value of the model in the controller, when i view the resulting HTML i see that the value is selected in the HTML code ,but not selected in the select control , and the select control displays an empty item.
Try this
<select
name="name"
id="id"
ng-options="option.name for option in v.data track by option.value"
ng-model="v.selected"
class="form-control inline-forms">
<option value="" selected>{{placeHolder}}</option>
</select>
and in controller
$scope.v = {data:[], selected:{}, placeHolder:""}
$scope.v.data = [{name:"nameOne", value:"valueOne"},{name:"nameTwo", value:"valueTwo"},{name:"nameThree", value:"valueThree"}]
$scope.v.selected = $scope.v.data[0]
$scope.v.placeHolder = "Click to Select"
According Angular documentation ngOption is better way to go than ngRepeat:
Choosing between ngRepeat and ngOptions
In many cases, ngRepeat can be used on elements instead of ngOptions to achieve a similar result. However, ngOptions provides some benefits:
more flexibility in how the 's model is assigned via the select as part of the comprehension expression
reduced memory consumption by not creating a new scope for each repeated instance
increased render speed by creating the options in a documentFragment instead of individually
Specifically, select with repeated options slows down significantly starting at 2000 options in Chrome and Internet Explorer / Edge.

I was using Bootstrap select for search and multiple select but the problem is when i am using $scope object in ng-repeat for options it's not working . I have given my codes below .
<select name="name" ng-model="city.id" class="selectpicker" data-live-search="true" ng-options="o._id as o.name for o in stateList" ></select>
<select name="name" ng-model="city.id" class="selectpicker" data-live-search="true" ><option ng-repeat="option in stateList" value="{[{option._id}]}">{[{option.name}]}</option>
I have used both options and ng-option methods but still the object didn't show up ...
This is my state object that need to be repeated in select...
$scope.stateList = [{"_id":"1","name":"www"},{"_id":"2","name":"bgg"}]
Hope you understand my problem and if you need any more details
pls leave a comment and i'm waiting for your suggestions...
I was having issues as well, but using nya-bootstrap-select
http://nya.io/nya-bootstrap-select/#!/
fixed it. It has something to do with bootstrap select's use of jQuery which doesn't always play nice with angular...this is written in Angular for use with Angular, so its more compatible...
I am facing some issue on select tab when using in ng-repeat.
On Stackoverflow i found many solution related to my broblem but i am not able to solve my broblem.
Here is my code..
on the top of page i define my controler
<ion-view view-title="Product" ng-controller="productCtrl as pd">
and on controller
self.pdata = response;
On html page my code is..
<div ng-if="pd.pdata.optionid.length > 0" class="prodetail" ng-repeat="x in pd.pdata.optionid">
<h5>{{x.title}}</h5>
<select name="{{x.title}}" ng-model="pd[x.title]" style="right:5px;">
<option ng-repeat="y in pd.pdata.optionvalue[x.option_id]" value="{{y.value_id}}" selected>{{y.title | uppercase}}</option>
</select>
</div>
here my select tab is in ng-repeat loop
so that every time my ng-model is define dynamically.
My Problem is:-extra blank option added using ng-repeat in select tag
modify your select tag like this, it's a bit mouthful but works alternatively you can also keep your option tag and remove ng-options from my select tag.
<select ng-init="pd[x.title] = pd[x.title] || pd.pdata.optionvalue[x.option_id][0].value_id" name="{{x.title}}" ng-model="pd[x.title]" style="right:5px;" ng-options="y.value_id as y.title.toUpperCase() for y in pd.pdata.optionvalue[x.option_id]">
</select>
here is a jsFiddle
Initially problem seems to be here
value="{{y.value_id}}"
see more here The empty option is generated when a value referenced by ng-model doesn't exist in a set of options passed to ng-options
use a hard coded empty value
<option value="" ng-if="false"></option>
I am getting empty Option field in select tag.
My code is shown below:
openSelectBoxModel="47"
openSelectList=[{id:""47",name:"text"}];
valuekey="id";
titlekey="name";
<select id="reportOpenSelectBoxSingle" size="6" ng-style='selectStyle' class="openSelectBox" ng-model="openSelectBoxModel" ng-change="changeFn()" >
<option ng-selected="openSelectBoxModel===item[valueKey]" ng-repeat="item in openSelectList" id="" ng-value="{{item[valueKey]}}" ng-title="{{item[titleKey]}}" ng-bind="item[titleKey]"></option>
</select>
Please help me to solve this problem.
You should not use ng-selected with ng-model.
The thing to do is to bind the selected item to your ng-model before displaying it.
//Also, instead of ng-repeat, you should use ng-option
As far as performance is regarded : ng-options does not create child scopes for every iteration. When angular performs its digest, your ng-repeat will slow it. If you have a list with hundreds of elements, you will feel a difference.
<select id="reportOpenSelectBoxSingle"
size="6"
ng-style='selectStyle'
class="openSelectBox"
ng-model="openSelectBoxModel"
ng-change="changeFn()" >
<option ng-repeat="item in openSelectList"
value="{{item[valueKey]}}"
title="{{item[titleKey]}}"
ng-bind="item[titleKey]">
</option>
</select>
Furthermore, you need to declare your variables inside a controller :
$scope.openSelectBoxModel="47";
$scope.openSelectList=[{id:"47",name:"text"}];
$scope.valuekey="id";
$scope.titlekey="name";
I am using ng-repeat on option in select.
<select ng-model="mymodel">
<option ng-repeat="p in persons" value="{{p.id}}">{{p.name}}</option>
</select>
$scope.persons= [
{id:1,name:"tester11"},
{id:2,name:'tester22'},
{id:3,name:'tester33'},
{id:4,name:'tester44'}
];
How can I make an option selectable means by default "tester33" should be selected
through use of ng-model.
I know it is achievable through ng-options. But I want to try this one.
Thanks in advance.
There is no perfect way to achieve this using ng-repeat, but here's a workaround:
<select ng-model="mymodel">
<option ng-repeat="p in persons" ng-selected="p.name=='tester33'" value="{{p.id}}">{{p.name}}</option>
</select>
This just sets the option with name='tester33' but the model won't get updated until the user changes select value explicitly
NOTE: This is not a recommended way, you must use ng-options for complete functionality
