As far as I know there currently is no multi-select field type. There is a dropdown type, but you can only select one of the dropdown values. Multi-select would allow the user to select multiple values. I need this feature, but I couldn’t find anything about it when searching this forum, the GitHub repo’s and the Taiga ‘tree’.
Currently, Taiga does not have a multi-select field type, but we appreciate your suggestion and will take it into account for Taiga next features.
Meanwhile, you may be able to simulate the behavior of a multi-select by using various checkboxes’ field types. Although it may not be as efficient as a dedicated multi-select field, it can help achieve a similar result.
Thank you for your interest in Taiga, and please feel free to let us know if you have any further suggestions or feedback.
