@23creative maybe you can give a clue?

This works now perfect when starting a new topic.

But when I edit a topic with e.g. 3 tags, edit screen shows only 1 tag selected. After I save the edited topic, all tags are lost.

Any ideas where to search for solution?

FINAL CODE HERE.
FOR CHECK BOXES.
(Difference from the upper one: fixed issue with tags with more than 1 word)

function displayTagElements($selectedTags, /* $userRole, */ $task){
   $html= array();
$tags = get_categories(array('hide_empty' => 0, 'taxonomy' => 'topic-tag'));
$selectedTagsArray = explode(',', $selectedTags);
if($userRole != 'bbp_participant' || $task != 'edit') {
    $html[] = "";
    foreach($tags as $tag) {
        $selected = '';
        if (in_array($tag->name, $selectedTagsArray)) {
            $selected = 'checked';
        }
        $html[] = "<input type='checkbox' name='bbp_topic_tags[]'".$selected." value='". $tag->name ."'>". $tag->name ."&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
    }
} else {
    $html[] = $selectedTags;
}

return implode('', $html);

Here is a working code. Hooray!

function displayTagElements($selectedTags, /* $userRole, */ $task){
   $html= array();
$tags = get_categories(array('hide_empty' => 0, 'taxonomy' => 'topic-tag'));
$selectedTagsArray = explode(',', $selectedTags);
if($userRole != 'bbp_participant' || $task != 'edit') {
    $html[] = "";
    foreach($tags as $tag) {
        $selected = '';
        if (in_array($tag->name, $selectedTagsArray)) {
            $selected = 'checked';
        }
        $html[] = "<input type='checkbox' name='bbp_topic_tags[]'".$selected." value=". $tag->name .">". $tag->name;
    }
} else {
    $html[] = $selectedTags;
}
return implode('', $html);

I think that there is also a need to change the surrounding <input></input> tag to <form></form>

Hi 23creative. Thank you.

It works quite well. I get checkboxes with existing tags.

The problem is that when I select some of them and create a new topic, the created topic doesn’t have these tags attached to it. Any ideas where is the problem?

The same happens with the profile page.

This is a similar issue: https://bbpress.org/forums/topic/user-profiles-page-have-sidebar-stacked-with-divi-theme-from-eleganttheme/

Is it possible to change the multiple select form into to separate checkboxes?

I think this line (that was added in fuctions.php) should be rewritten:

$html[] = '<select class="chzn-select" multiple="multiple" name="bbp_topic_tags[]" id="bbp_topic_tags">';
