Hello,
Is it possible to allow a member of dropdownbox widget in mapp View to have its sub-members, so dropdownbox widget can allow more choices after a member is chosen?
On the other hand, is it possible to allow texts in a member of a dropdownbox widget to change? Just like what can text snippet do in a textoutput widget?
Thank you
It’s possible to change the entries in a DropDownBox using the dataProvider property (see: B&R Online Help).
You could update this based on what the user has selected. However, a cleaner approach might be to have a second dropdown box populate/enable depending on the selections made in the first box. Otherwise, the value of the second selection will end up in the variable that holds the first selection and that could get messy.
