I inserted several combo boxes into a document, all seems to be fine until I reopen the document then all the lists are missing, when the dropdown box is clicked it’s just empty, help would be appreciated.

Could you kindly tell us how you populated the combo boxes with options and which version of LO you are using?

I managed to sort it out, not 100% sure how I did it but it may have been in the form properties, under the data tab then select the appropriate content table. I’m using linux mint 19.1, libreoffice Version: 6.0.7.3. Thanks for your help.
