Sorry if this is a silly question, but how do you insert a combobox with checkboxes inside and have all of them visible on the screen. In InfoPath, you can have a list of items and increase the height of the control to show all the items and have checkboxes beside each item to show that it's multi-select.
In PowerApps, there only seems to be a drop-down menu control with no indication that you can select multiple items. This is poor UX design. All of the other Microsoft applications have this standard control (or at least multiple checkboxes), so it's baffling that PowerApps doesn't (at least not in the standard controls dialog). This in addition to other basic controls and functionality missing is making the switch from InfoPath/SharePoint Forms to PowerApps pretty frustrating.
Does anyone know how to do it?
