Design screen - controls dissappeared again

See my similar topic from Jan 18. Today experiments with implementing another datepicker (by tempusdominus). I tried to drag and drop a container onto the form, intending to include it afterwards into an input-group (datetimepicker1). When I moved the container in direction of the design screen the design screen went blank of controls before I could drop the container on the design screen. There at first were some characters and something like an input field on design screen. Greyed out. I only could guess that I had put a div into property style which was like the input control which was already placed. I forgot that I had not deleted the style property of form1. When I deleted this style, the screen became completely blank as shown in attached screenshot. I thought I should mention this as it had happened before and a bugfix was intended.

Can you reproduce this? If we had a step by step for this, I’m sure we could figure out what is going on.

Here are the latest log entries. The latest (14:47….) is the original project Fristen. Fristen opened again, with design screen. The copy (FristenExperimente) did not until I had repaired a property entry.

A zip file of the faulty project is attached.

Certainly there are errors I caused in the code while I implemented the new datepicker step by step.

This datepicker needs “data-target="…e.g…#datetimepicker1" within the html of the input control. Because I thought this not to be a class I wondered where to insert it in the control’s properties. So I obviously had done the wrong thing putting it into style property.

After the crash I finally removed this entry from style property and the design screen reappeared.

I hope to find where to apply data-target=“datetimepicker1” to the input control without causing the design screen crash again.

It is easy to write the complete input-group code with the divs and the control in html code. Yet I did and do not get how to do this with html without interfering with the divs and the input control already positioned in design screen.

Very strange. After having the design screen displayed again, with all controls,

I again entered texts like “data-target …” into style properties. The design screen did not disappear again …

This leaves the one and only idea that the empty design screen happened while I attempted to drag and drop a container.

My construction still does not work. I assume that this is another issue.

I attempt to get this done:

            <div class="input-group date" id="datetimepicker4" data-target-input="nearest">

                <input type="text" class="form-control datetimepicker-input" data-target="#datetimepicker4"/>

                <div class="input-group-append" data-target="#datetimepicker4" data-toggle="datetimepicker">

                    <div class="input-group-text"><i class="fa fa-calendar"></i></div>

                </div>

            </div>

Bernd

Next step. Tried to do it without icon.

Inserted the needed “data-toggle=“datetimepicker” data-target="#datetimepicker1" into style property of input control. Design disappeared. Deleted the entry at style property: Design screen with all controls shown.

data-toggle and data-target are “attributes”. So I could enter these in attribute property, without design screen crash.

Now I get these errors:

I was just typing a message to that effect - those are attributes, not styles.

When I paste this into the attributes of a BS4 Input control, I do not get an error.

I did not get this message yet. But I detected this (attribute property) meanwhile. Then I got another error, which comes from tempusdominus. See my email answering one of your emails directly. Somebody suggested a workaround to use class datetimepicker instead of class datetimepicker-input. Without -input the datepicker appears, w/o error, but rather invisible behind the next controls. So the initial question/issue is resolved. Design screen crash happened presumably because I put attributes at style property.
Thanks
