@DenisChenu, @tpartner, did you ever create custom themes for 5.x or 6.x using the theme option setup directly at config.xml?

We are facing this issue and wonder if we are doing something wrong at the implementation or if this is a bug at Limesurvey which prevents users from defining their own additional logos.

@Mazi, no, I have not tried to add an option dropdown.

I see code blocks that I feel responsible for [background file] and [brand logo file] in the beging of file [views/themeOptions/options_core.php]. If I append below code to this file then issues gets resolved. But we can not edit LS core files make cutomizing templates. I am sharing this obsevation so that it may help in tracing the issue.

//------------------------------- brand logoLeft file
$brandlogoLeft = '';
$logoLeftfileOptionsInherit = '';
$logoLeftfileInheritPreview = '';
$logoLeftfileInheritFilename = '';
$optgroup = '';
foreach ($aTemplateConfiguration['imageFileList'] as $image) {
if ($image['group'] != $optgroup) {
if ($optgroup != '') {
$brandlogoLeft .= '</optgroup>';
}
$brandlogoLeft .= '<optgroup label="' . $image['group'] . '">';
$optgroup = $image['group'];
}

$brandlogoLeft .= '</optgroup>';
if ($oParentOptions['brandlogoLeft'] == $image['filepath']) {
    $logoLeftfileInheritPreview  = $logoLeftfileInheritPreview . $image['preview'];
    $logoLeftfileInheritFilename = $logoLeftfileInheritFilename . $image['filename'];
}
$brandlogoLeft .= '<option data-lightbox-src="' . $image['preview'] . '" value="' . $image['filepath'] . '">' . $image['filename'] . '</option>';

}

$aOptionAttributes['optionAttributes']['brandlogoLeftfile']['dropdownoptions'] = $brandlogoLeft;

Issue or misfeature in LimeSurvey : https://bugs.limesurvey.org/view.php?id=18880

The 2 image list are fixed by code there are no way to set another dropdown to imageList

Remind : we need an attribute or something other to tell this dropdown are a imageList

Well, when using our own options.twig file we can easily have multiple logos. When using the config.xml, this does not work. So I consider this a regression.
