in the 2019 version, is there a way to start with the sidebar collapsed?
Try 2020 which supports the advanced setting Tools → Advanced Settings → AdminLTE Layout class = “sidebar-collapsed”.
Ok, I did try this. The 2020 supports the collapsed sidebar on page startup, but this version has an issue with both the datetime picker and time picker fields not sizing to support the width of the picker extensions. The timepicker is so compressed in width that you can’t see any of the time picker selections… Any ides why this may be happening.
You probably have some old CSS, check your project, remove old CSS, generate all scripts again (especially the *.css files). Clear temp. files in your browser to make sure the new *.css are used.
