• The jira.max.issue.filter.dropdown.items property will change the amount of filters displayed in theIssues drop-down of JIRA's navigation bar. See screenshot:

To change the amount of filters displayed in the Issues drop-down, edit or create the jira-config.properties file in <jira-home> directory by adding the following line:

jira.max.issue.filter.dropdown.items=30

 In the above example the number of filters displayed will be set to 30.

 Note this does require a restart of JIRA to take effect.
