title: How to skip drawing an item when a Grid is populated via an Repeater in qml?
body: <p>I want to fill a Grid with a Repeater but not all cells should get an Item. How to do that?</p>
  
  <pre><code>Rectangle {
      id: base
  
      Grid {
          id: grid
          anchors.fill: parent
          columns: 30
          rows: 20
  
          Repeater {
              model: grid.columns * grid.rows
              delegate: Item {
                  // How to skip this at row 5, column 3, for example
                  width: grid.width / grid.columns
                  height: grid.height / grid.rows
              }
          }
      }
  }
