As we saw in the previous recipes, adding a web fragment is pretty easy. However, the job doesn't always end there. In many cases, we would want to limit the web item based on a set of conditions.
For example, an Edit link on an issue should only appear for people with edit permission on an issue. The Administration link should appear only if the user is a JIRA administrator. In this recipe, let us look at how we can implement conditions for displaying web fragments.
It is possible to add one or more conditions to a web section or web item. In the latter case, the conditions element is used, which is a collection of condition/conditions elements and a type attribute. The type attribute is either the logical AND or OR.
For example, the following condition specifies that the user should have either the admin permission or use permission in a project before he/she can see the web fragment that has the condition on it.
<conditions type="OR">...
