[CLOSED] Open ComboBox on Click?

Is there some action/script I can use to open the ComboBox (as if I clicked on the little triangle on the right) when any part of the combobox is clicked?

Hi,

It is default behaviour if Editable="false"
If you need editable option then expand manually on focus

Code:

---

<Focus Handler="this.expand();" />

Thanks, please mark as [CLOSED]
