Show or hide specific elements based on parameters using ng-show in Angular

One challenge I am facing is how to manage a menu with multiple buttons that open submenus without using a massive switch statement in my code. Instead, I want to try something different:

In the HTML file, I call the function toggleVis and pass the name of the element to be toggled as a parameter:

<ul class="sidebar-bottom-list" ng-controller="MenuController">
<li>
    <a href="#/dossier" ng-click="toggleVis(showSubmenuDos); go('/dossier')" ng-class="class" class="sidemenuItem"><span class="glyphicon glyphicon-folder-open"> </span>Dossiers</a>
    <div class="list-group narrow-list-group no-padding-bottom slider-top-bottom" ng-show="showSubmenuDos" ng-class="active">
        <a href="#" class="list-group-item" ng-class="dosMenuItems(0)">lijst</a>
        <a href="#" class="list-group-item" ng-class="dosMenuItems(1)">algemeen</a>
        <a href="#" class="list-group-item" ng-class="dosMenuItems(2)">partijen</a>
        <a href="#" class="list-group-item" ng-class="dosMenuItems(3)">documenten</a>
        <a href="#" class="list-group-item" ng-class="dosMenuItems(4)">notas</a>
        <a href="#" class="list-group-item" ng-class="dosMenuItems(5)">royementen</a>
        <a href="#" class="list-group-item" ng-class="dosMenuItems(6)">urenregistratie</a>
        <a href="#" class="list-group-item" ng-class="dosMenuItems(7)">voortgang</a>
    </div>
</li>
<!-- imagine more menu items like this one -->

Next, in my main.js file, I have defined the toggleVis function as follows:

app.controller('MenuController', function($scope, $location) {

//can be triggered by ng-click="go('/path')"
$scope.go = function(path) {
    $location.path(path);
};

//toggle visibility
$scope.toggleVis = function(param) {
    //$scope.{param} = !$scope.{param}
    alert(param)
    $scope.param = !$scope.param;
    //param.ngShow = !param.ngShow;
    //$scope.this = !$scope.this;
}
});

I have attempted different approaches but nothing seems to work.
Is there a better way to achieve what I need, or perhaps an improved solution?
I would appreciate a detailed explanation in your response.

To easily switch between views, you can follow the example below. Simply toggle the value on click using var = !var and incorporate it with ng-show:

var myApp = angular.module('myApp',[]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app="myApp">
  <button ng-click="show = !show">Toggle</button>
  <p ng-show="show">I am being displayed and hidden alternatively!</p>
</div>
