By default it expects your elements to have `label` and `children` properties for node display text and child nodes respectively. It'll also make use of a `selected` attribute to manage selected states. If you would like to pick out nodes by ID rather than reference it'll also use an `id` attribute. Those attributes can all be changed, for example: ```html <div ng-controller="MyCtrl as fancy"> <div ivh-treeview="fancy.bag" ivh-treeview-id-attribute="'uuid'" ivh-treeview-label-attribute="'text'" ivh-treeview-children-attribute="'items'" ivh-treeview-selected-attribute="'isSelected'"> </div> ``` IVH Treeview attaches checkboxes to each item in your tree for a hierarchical selection model. If you'd rather not have these checkboxes use `ivh-treeview-use-checkboxes="false"`: ```html <div ng-controller="MyCtrl as fancy"> <div ivh-treeview="fancy.bag" ivh-treeview-use-checkboxes="false"> </div> ``` There's also a provider if you'd like to change the global defaults: ```javascript app.config(function(ivhTreeviewOptionsProvider) { ivhTreeviewOptionsProvider.set({ idAttribute: 'id', labelAttribute: 'label', childrenAttribute: 'children', selectedAttribute: 'selected', useCheckboxes: true, expandToDepth: 0, indeterminateAttribute: '__ivhTreeviewIndeterminate', expandedAttribute: '__ivhTreeviewExpanded', defaultSelectedState: true, validate: true, twistieExpandedTpl: '(-)', twistieCollapsedTpl: '(+)', twistieLeafTpl: 'o', nodeTpl: '...' }); }); ``` Note that you can also use the `ivhTreeviewOptions` service to inspect global options at runtime. For an explanation of each option see the comments in the [source for ivhTreeviewOptions][trvw-opts]. ```javascript app.controller('MyCtrl', function(ivhTreeviewOptions) { var opts = ivhTreeviewOptions(); // opts.idAttribute === 'id' // opts.labelAttribute === 'label' // opts.childrenAttribute === 'children' // opts.selectedAttribute === 'selected' // opts.useCheckboxes === true // opts.expandToDepth === 0 // opts.indeterminateAttribute === '__ivhTreeviewIndeterminate' // opts.expandedAttribute === '__ivhTreeviewExpanded' // opts.defaultSelectedState === true // opts.validate === true // opts.twistieExpandedTpl === '(-)' // opts.twistieCollapsedTpl === '(+)' // opts.twistieLeafTpl === 'o' // opts.nodeTpl =(eh)= '...' }); ``` ### Filtering We support filtering through the `ivh-treeview-filter` attribute, this value is supplied to Angular's `filterFilter` and applied to each node individually. IVH Treeview uses `ngHide` to hide filtered out nodes. If you would like to customize the hide/show behavior of nodes as they are filtered in and out of view (e.g. with `ngAnimate`) you can target elements with elements with the `.ivh-treeview-node` class: ```css /* with e.g. keyframe animations */ .ivh-treeview-node.ng-enter { animation: my-enter-animation 0.5s linear; } .ivh-treeview-node.ng-leave { animation: my-leave-animation 0.5s linear; } /* or class based animations */ .ivh-treeview-node.ng-hide { transition: 0.5s linear all; opacity: 0; } /* alternatively, just strike-through filtered out nodes */ .ivh-treeview-node.ng-hide { display: block !important; } .ivh-treeview-node.ng-hide .ivh-treeview-node-label { color: red; text-decoration: line-through; } ``` ***Demo***: [Filtering](http://jsbin.com/zitiri/edit?html,output) ### Expanded by Default If you want the tree to start out expanded to a certain depth use the `ivh-treeview-expand-to-depth` attribute: ```html <div ng-controller="MyCtrl as fancy"> <div ivh-treeview="fancy.bag" ivh-treeview-expand-to-depth="2" ivh-treeview-use-checkboxes="false"> </div> ``` You can also use the `ivhTreeviewOptionsProvider` to set a global default. If you want the tree *entirely* expanded use a depth of `-1`. Providing a depth greater than your tree's maximum depth will cause the entire tree to be initially expanded. ***Demo***: [Expand to depth on load](http://jsbin.com/ruxedo/edit?html,js,output) ### Default Selected State Whe
