Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

UMG Combobox Arrow Image not used

When I create an UMG combobox and set the image for the down arrow in the style section of the details panel, then the image itself is being used, but not its color. Even if I set the tint value to some color, that color is not being used. It always stays at this dark default color.

Seems to be a bug. Any ideas how to work around that?

Hello haimat,

This is a known issue (UE-18194) that has been submitted to the developers for further consideration. I have provided a workaround below that my be viable depending on your needs. I hope that this information helps.


  1. Create a combo box string and add it to the designer tab

  2. Create an empty material (this will be used to hide the current down arrow) alt text

  3. Apply the empty material as the image for the down arrow

  4. Create an image widget

  5. Set the image widget's visibility to "Self hit invisible" alt text

  6. Set the image widget to what you would like your new down arrow to be alt text

  7. Place the image widget over the now empty area that used to contain the down arrow

Make it a great day

Hmm, you mean to place a floating image on top of the dropdown box? But wouldn't that overlap with the text within the dropdown box, if that is long enough?!

If you make the image the same size as the original arrow you will see no difference. The Combo box string cuts off any element that are too long any way. I have provided two extremely zoomed in pictures to show a selection that is being cut off. On one side you will see my replacement and on the other you will see the default.

As you can see here changing the image made no difference.
