Hi Miyako, Your example database: https://doc.4d.com/4Dv16/4D/16.4/Pop-up-MenusDrop-down-Lists.300-3998943.en.html shows assigning a “Form” object to store the popup’s current state. The object assigned to the

Re: Popup/Dropdown element 0

This is an old-style process variable declared as text array. The popup/dropdown displays the 0 element value properly when the array is empty, but does not display it when the array has elements. that has not been my experience (the array is not empty) to be precise, I used v17.232641 on Mojave

Re: Popup/Dropdown element 0

the example DB I posted earlier in this thread uses New list and OBJECT SET LIST BY REFERENCE. the list can be totally dynamic, it does not need to exist in the toolbox. when you use default values, you essentially using text arrays constants. that is why, for example, if the popup menu is associ

Re: Popup/Dropdown element 0

I see, it uses a list for the choices but can display a value not in the list. That will be useful for those cases where the values come from a list. In this case the popup choices are set dynamically based on other values. This should also work with the “Default Values” property, right? Is the

Re: Popup/Dropdown element 0

The v15 and v16 documentation doesn’t mention using a text variable for a popup/dropdown. Do you have some info on how that would work? https://doc.4d.com/4Dv16/4D/16.4/Pop-up-MenusDrop-down-Lists.300-3998943.en.html Jim Crate > On Jan 28, 2019, at 7:16 PM, Keisuke Miyako via 4D_Tech > <4d_tec

this is v17 but I can confirm that it is possible to display a default value, provided you associate the popup menu to "list item value (not ref.)" https://forums.4d.com/4DBB_Main/x_User/298210/files/28213957.zip using text arrays is old school, it's much easier to associate a popup menu to a tex

Popup/Dropdown element 0

I’m pretty sure that popup/dropdowns used to display the value stored in the array’s element at index 0 in earlier versions of 4D, if you set the array’s value to 0. I have code in the system that uses that to display a title for a popup that is separate from the values, or to display a value th
