 <div class="col-lg-10 col-md-10 col-sm-10 col-xs-10 set_padding_0 social_icons_section"> <div class="social_icon_radio_toggle"> <label class="linkedin"> <input type="radio" name="registration_options" checked="checked" ng-click="option='linkedin'" ng-init="option='linkedin'"> <span><i class="fa fa-linkedin"></i> </span></label> <label class="facebook"> <input type="radio" name="registration_options" ng-click="option='facebook'"> <span><i class="fa fa-facebook"></i> </span></label> </div> <div> <input class="form-control margin_top_4" placeholder="www.linkedin.com/example" type="text" ng-show="option == 'linkedin'" ng-hide="option == 'facebook'"> </div> <input class="form-control margin_top_4" placeholder="www.facebook.com/example" type="text" ng-show="option == 'facebook'" ng-hide="option == 'linkedin'"> </div> 

Answer 1

You should use the directive ng-model to track the value of your 'option' property. Then set per every radio button the corresponding ng-value.

And take into account, that ng-show and ng-hide works in similar ways. It is not necessary to use both at the same time. ng-hide = hide the element if the expression = true ng-show = show the element if the expression = true

<label class="linkedin" >
<input type="radio" name="registration_options"  ng-model="option" ng-value="'linkedin'">
<span><i class="fa fa-linkedin"></i> </span></label>
<label class="facebook" >
<input type="radio" name="registration_options" ng-value="'facebook'" ng-model="option">
 <span><i class="fa fa-facebook"></i> </span></label>

<input class="form-control margin_top_4" placeholder="www.linkedin.com/example" type="text" ng-show="option == 'linkedin'">
<input class="form-control margin_top_4" placeholder="www.facebook.com/example" type="text" ng-show="option == 'facebook'">
