Summary

Scroll option is not available when the Issues in Epic list (on issue view page) exceeds issue page

Steps to reproduce

1. Add issues in epic on an issue.
2. Minimize the browser size
3. Click *Issues in Epic option gear icon
   
4. Some options will not be visible

Expected Result

User can scroll to view the hidden options

Actual Result

Scrolling is not possible

Suggestion

JIRA should have scrolling option within the Issues in Epic list

Workaround

Add the following to Jira's Announcement Banner:

<style type="text/css">

div#actions_10401_drop {
    overflow: scroll;
    height: 600px;
}

div#actions_10401_drop::before {
    content: "This menu is scrollable";
    text-align: center;
    font-style: italic;
    display: block;
    color: navy;
    font-weight: bold;
    margin-top: 2px;
}

</style>

The problem here is that the workaround needs to be applied to each and every option button as each button has a unique id eg. actions_10401_drop

To find the id :

1. Open the Developer Tools option
2. Select the Elements bar
3. Open the drop down
4. Select an element on the page to inspect it
5. Here we can see that the id is actions_10401_drop
6. 
7. Replace the id on the announcement banner script accordingly after "div#".
