I would like to have a combo box contain variables and have the value of the variable displayed when the combo box is opened. Can this be done?

Thanks, Joe

Hi Joe,

At the time being the ComboBox content is static, which can only be specified in editing mode. So this could not be done yet.

A possible workaround is to use the Table element, which can dynamically add/edit/remove the content in simulation mode. Using a button to show/hide that table might achieve similar result.

The dropdown style assets specify whether or not the han solo jacket listing is constantly displayed or whether the list is displayed in a drop-down.

You will need to define your own Javascript function beforehand. You can make use of the Script element for that purpose.

I know it’s still not possible to have a combo box contain variables and have the value of the variable displayed when the combo box is opened up to this moment.

This enhancement makes table editing much easier as you don’t need to be too careful, and every mistake could be undone.

Yes, it is possible to have a combo box display the value of a variable when it is opened. The exact steps to accomplish this may depend on the programming language or software you are using, but in general, you can follow these steps:

  1. Create a combo box and populate it with the desired variables.
  2. Set the “default value” or “selected value” of the combo box to the desired variable. This can often be done using the “value” property of the combo box.
  3. Add an event listener to the combo box that triggers when the user opens the drop-down list.
  4. In the event listener, get the selected value of the combo box (which should be the default value you set earlier) and display it in the desired location. This can be done using a label or other UI element.

Again, the exact steps may vary depending on the specific language or software you are using, but this general approach should work in many cases.  storm drain cleaning fort lauderdale
