I'll preface this by saying we do not have ScriptRunner(despite our wishes)
We are trying to hide the summary field in a specific screen, since we'll be using a plugin to fill with the concatenation of other fields.
On the create screen however, we used a JS script in the field configuration to fill it with a standard value, so as to not be empty.
This is the script we have on the Field Configuration Summary Description:
<script type="text/javascript">
if (document.getElementById("summary").value == "") {
document.getElementById("summary").value = "Do not Edit";}
</script>
Now we are trying to hide it. Any help in that regard.
