Checkboxes in Gallery - only one choosable, disable the others

Posted on by Neewy

Hi,
I would like to build a configurator. I have several screens with galleries of which you can choose one line of each gallery. I can jump back within the configuration and change the selection. To show which selection has been made I have added a checkbox. Unfortunately it is possible to select multiple checkboxes within one gallery. How can I change this?

Maybe it is possible to disable the checkboxes an the Save-buttons of the other lines?

When the configuration is finished all checkboxes should be unchecked again.

Can anyone help me? Maybe you have another idea how I can solve the problem?

Beste regards

Neewy

Hello,
thanks for your answer.
The checkboxes in the gellery are somehow grouped. If I make this setting it is valid for all of them and the user can't make any changes. How can I access the individual checkboxes? Once one is checked the rest should be disabled until ithe one becomes unchecked.

i get it, i think
here is a gallery with three options. The label17 is the option text.
when the user selects the checkbox, OnCheck =
If(IsBlank(_SelectedOption) , UpdateContext({_SelectedOption: Label17.Text}))
OnUncheck =
UpdateContext({_SelectedOption: ""})
Displaymode =
If(_SelectedOption = Label17.Text || IsBlank(_SelectedOption), DisplayMode.Edit,DisplayMode.View)

now when the user select a box before another box can be selected the user needs to uncheck the current selected box.

will that help? in the above pic the user can click option 2 or 3
