    Default Answered: Configure collapse control for panels

    Answered: Configure collapse control for panels


    I'm looking for a way to configure panels so that the collapse tool that appears with collapsible: true renders on the left hand side of the panel, before the title object.

    There's a hacky way suggested under collapseFirst on Ext.panel.Panel's documentation page, but this can adversely impact render time if you're rendering a lot of collapsible panels at the same time.

    Is there, or are there plans to develop, something like a collapseAlign configuration?

  2. ..ok. I do believe I got it looking at Ext.panel.Header.

    for anybody else looking into this, my solution was:

    Code:
    Ext.define('myapp.view.repeatingpanel', {
        extend: 'Ext.form.Panel',
        collapsible: true,
        header: {        
            listeners: {
              beforerender: function(header) {
                  var collapsetool = header.tools[0];
                  header.insert(0,collapsetool);
                  //this.log('before render',header);
              },
          }
        }

    If you want total control, you can add an item to the header, the header is a container using hbox layout.

    Would I need to replace the collapse tool with a tool of my own that mimics it, or could I specify the native items in the order I want them using the header configuration?

    How would I do that? (Specify the order of the native items, like the title component, collapse tool, etc?)

    header: {
    collapsetool,
    title
    }
