Hello,
I have a form with many section.
Some section, randomly, show a different line separator…

Check this snippet, the Test3 section:

For your information, the same code on my applications, the “double” line is on Test2 and Test1 section.

Any idea?

Hello @algianotti ,
As far as I can see , in the example that you attached everything works work fine.
I’m afraid the description of the issue is not clear for us. Could you please describe in more detail the strange behavior of the “section” line?

Sorry, the problem is that the line of the Test3 section, is more thick than the others.
Verified also with other screens.

Hello @algianotti ,

Sorry, the problem is that the line of the Test3 section, is more thick than the others.
By default, all “section” lines have a height 1 px.
Unfortunately, I can’t repeat the described issue. Could you please provide a screenshot where the problem with line can be seen?

Also in the developer tools, you can go to the “Elements” tab and check the styles attached to the class .webix_section::before. They should be something like this:

.webix_section::before {
    content: "";
    display: block;
    width: 100%;
    height: 1px;
    background-color: rgb(218, 222, 224);
    position: absolute;
    top: 50%;
}

Could you please share this setting too?
