Hi,

I have entered this to insert a floating header: <style type="text/css" data-author="Tony Partner">
 
@media only screen and (min-width: 768px) {
#question{QID} .answer-container {
position: relative;
max-height: 500px;
overflow: scroll;
}
 
#question{QID} table.subquestion-list {
text-align: left;
position: relative;
border-collapse: collapse;
}
 
#question{QID} table.subquestion-list thead th,
#question{QID} table.subquestion-list thead td {
position: sticky;
top: 1px;
z-index: 1000;
background: #DDDDDD;
border: 0 none;
box-shadow: -1px 0 #000000, 0 1px #000000, 1px 0 #000000, 0 -1px #000000;
}
 
#question{QID} table.subquestion-list .ls-heading-repeat {
display: none;
}
}
</style>

However because there are two headers, they seem to overlap when I scroll. Is there any way to keep it "fixed"?
Also, is there a way to show the gridlines that are present in the rest of the question?

Thank you.

     

We cannot help with such limited information.

You didn't answer the questions at the top of the first post so we have no clue about your LimeSurvey environment and you didn't attach a sample survey so we can't see the code used to insert the extra headers.

Please refer to the English version of the survey.

Thank you.

I hope you did NOT attache the International Space Station to this thread. I am a little afraid to open that file now...

It's hopefully a .LSS file, not an .ISS file.

Haha, oops!

Try this:
