Keep md-select open until clicked outside - AngularJS


I am using md-select rendering md-checkbox wiyth a selectAll option.

If I select all, all checkboxes are selected and the dropdown closes which is expected.

How do I trigger not to close the dropdown when any value other than All is selected and close it on outside click?

var app = angular.module('BlankApp', ['ngMaterial', 'ngMessages']);

app.controller('mdSelectController', function($scope, $mdPanel, $mdSidenav, $mdDialog) {

  $scope.helpers = [{
      name: 'All',
      selected: false
    },
    {
      name: 'Ron',
      selected: false
    },
    {
      name: 'Jim',
      selected: false
    },
    {
      name: 'John',
      selected: false
    },
    {
      name: 'Paul',
      selected: false
    },
    {
      name: 'Jeremie',
      selected: false
    }
  ];

  $scope.changeCheckbox = function(rating) {
  console.log(rating)
    if (rating.name === 'All' && rating.selected === true) {
      _.forEach($scope.helpers, function(item) {
        item.selected = true;
      });
    }
    if (rating.name === 'All' && rating.selected === false) {
      _.forEach($scope.helpers, function(item) {
        item.selected = false;
      });
    }
    if (rating.name !== 'All') {
      console.log("Not all");
      _.forEach($scope.helpers, function(item) {
        if (item.name === 'All') {
          item.selected = false;
        }
      });
    }
  };

});

  <md-input-container>
    <label>Rating</label>
    <md-select id="ratingDropdown" ng-model="automationRatingObj" md-container-class="ratingDropdown" required="required">
      <md-option ng-value="rating" ng-repeat="rating in helpers track by $index">
        <md-checkbox ng-model="rating.selected" aria-label="Select a Rating" ng-change="changeCheckbox(rating)"></md-checkbox>{{rating.name}}
      </md-option>
    </md-select>
  </md-input-container>

</body>

</html>

Please advice. I checked the API of md-select but they dont have any code to keep the dropdown open. Also, how do I disable click on the text inside md-select and enable click only for checkbox?


Solution

  • You want the dropdown to close when clicking all, but to remain open when clicking any other item. You can check for which value you are at in ng-repeat and add $event.stopPropagation(); to all objects without 'All'. You can do this using ternary operator on ng-click on md-option: ng-click="rating.name != 'All' ? $event.stopPropagation(): ''"

    var app = angular.module('BlankApp', ['ngMaterial', 'ngMessages']);
    
    app.controller('mdSelectController', function($scope, $mdPanel, $mdSidenav, $mdDialog) {
    
      $scope.helpers = [{
          name: 'All',
          selected: false
        },
        {
          name: 'Ron',
          selected: false
        },
        {
          name: 'Jim',
          selected: false
        },
        {
          name: 'John',
          selected: false
        },
        {
          name: 'Paul',
          selected: false
        },
        {
          name: 'Jeremie',
          selected: false
        }
      ];
    
      $scope.changeCheckbox = function(rating) {
      console.log(rating)
        if (rating.name === 'All' && rating.selected === true) {
          _.forEach($scope.helpers, function(item) {
            item.selected = true;
          });
        }
        if (rating.name === 'All' && rating.selected === false) {
          _.forEach($scope.helpers, function(item) {
            item.selected = false;
          });
        }
        if (rating.name !== 'All') {
          console.log("Not all");
          _.forEach($scope.helpers, function(item) {
            if (item.name === 'All') {
              item.selected = false;
            }
          });
        }
      };
    
    });
