Sorry for the hassle with this one @bmurata.
The reason is that the option to select a specific item in the ComboBox/DropDown control was implemented recently in Mockups 3 for Desktop and is not available yet in myBalsamiq, which uses a different version of our editor.
We plan to bring all the version 3 goodness in the next major version of our web version but for now, here is a workaround that can allow you to show a selected item in the control:
- Add a rectangle and set its size to match one item’s size
- Set the rectangle border to borderless
- Set the opacity to 50%
- Choose the color and overlay the ComboBox control
You can even group the controls together to make the selection easier to move if needed.
Hope this helps! Let us know if you need anything else.
