The PocketQuery macro is always displayed as "block", not "inline". This is a setting in the Confluence macro code itself which cannot be adjusted with a setting at the moment.

But you can use the following CSS snippet and add it to your custom Template:

<style>
  .pocketquery-view-container
  { display: inline-block; }
</style>
CODE

Please be aware of the following: this will affect all PocketQuery macros on the page, they will all be displayed inline.
