I created a combobox with pagination (pageSize : 20, maxHeight : 200). When the first time the combo is loaded. It will get data from store and look up for the id and get display value. When I click on the combo, it will show all the 20 records perpage without vertical scrolling, which means the maxHeight has no effect. Please see my image. However, if u change the combo value, the scrolling will appear. The issues only appear when first time click on the combo.
Anybody having same issues?
