    Default Unanswered: Nested List with Disclosure only on Leaf

    Unanswered: Nested List with Disclosure only on Leaf


    Currently I am using the getItemTextTpl configuration of the Ext.NestedList to check whether the record is a leaf. If it is I modify the template to include an element with "x-list-disclosure" as the class. This works, but is messy.

    Is there a way to use onItemDisclosure and only have it create disclosure icons on leaf items?

    Thanks

    Inspect the DOM... is there a CSS change between if a row is a leaf or not? You may be able to hide the icon via CSS.

    Not Leaf
    HTML Code:
    <div class="x-list-item">
        <div class="x-list-item-body"><span>Today</span></div>
       <div class="x-list-disclosure"></div>
    </div>
    Leaf
    HTML Code:
    <div class="x-list-item">
        <div class="x-list-item-body">
            <span class="x-list-item-leaf">
                <div class="leaf-node">
                     <span>Torrance</span>
                </div>
            </span>
        </div>
        <div class="x-list-disclosure"></div>
    </div>
    I don't think there is a selector that can find
    HTML Code:
    .x-list-disclosure
    from
    HTML Code:
    .x-list-item-leaf
    .
    Thanks for the idea. I'll play around with it some more.

    So what I ended up doing is adding 2 listeners to the nested list component that adds the class leafList when all the nodes are leafs and branchList when there is a node with children in the list. Then I use some CSS to hide the buttons.

    Here's the relevant JS and CSS.
    Code:
                cardswitch:function(list, newCard, oldCard, index, animated) {               var isLeaf = true;
                   newCard.store.each(function(record, index, records) {
                       if (!record.get('leaf')) {
                           isLeaf = false;
                       }
                 });
    
    
                 if (isLeaf) {
                    this.addCls('leafList');
                    this.removeCls('branchList');
                 }
                 else {
                     this.addCls('branchList');
                     this.removeCls('leafList');
                 }
            }
    Code:
            render:function(list) {
                this.addCls('branchList');
            }
    HTML Code:
    .branchList .x-list-disclosure{    display: none;}
