Summary

The width of the suggested watcher list may sometimes not be enough to differentiate users when they're listed on multiple directories or have long and similar names.
This how to article provide an unsupported addition to the announcement banner to tweak the width of the auto-suggestion watcher picker light box that appears once you start typing.

JRASERVER-71262 - Getting issue details... STATUS

Environment

Validated in Jira 7.

Solution

Add the following code snippets to the announcement banner in Jira.

The default width for that field is 218px, so you may test values that work best for you:

<style type="text/css">
#watchers-multi-select {
    width: 260px !important;
}
</style>

Or this one, that would move the watcher selection box to the left. Note the second value should be slightly bigger than the firsts just for symmetry's sake. Again, test to reach a value that works best for you:

<style type="text/css">
#watchers-multi-select {
    width: 280px !important;
}
#inline-dialog-watchers {
    width: 300px !important;
}
</style>
