HTML in Personal Boxes

I’m trying to add HTML codes to personal boxes to be include in OJS of our journal but I couldn’t. There is a way to do this in versions 3.X ?
Thanking in advance and regards,

Before you post your question, check out the user guides and video tutorials at PKP Docs and search the forum to see if someone else had the same question.

When you post your question give as much detail as possible, including the following:

  • Application Version - e.g., OJS 3.1.2
  • Description of issue
  • Steps you took leading up to the issue
  • What you tried to resolve the issue
  • Screenshots
  • Error log messages if applicable

You can post in any language, but please note there is a Spanish OJS forum and a German category on this forum.

Did you have a look at the Custom Block Manager Plugin?

The Plugin management interface can be found at:
Management > Website Settings > Plugins > Generic Plugins > Custom Block Manager

Once the plugin is enabled, blocks can be added, edited and deleted through this
interface, using the "Manage Custom Blocks" function.

The added custom blocks will per default appear in the right sidebar, but this
can be changed in:
Management > Website Settings > Appearance > Layout > Sidebar Management.
