Provides you with a potential workaround for H5P content that won't show in tabs, accordions,…
PLEASE NOTE: I gave some of my free time to create this plugin. Using it and its source code is absolutely free. I don’t want any money from you. However, if you like this plugin, I kindly ask you to make a one-time donation of 2.50 EUR to the Rainforest Coalition (https://www.rainforestcoalition.org/donations/) — or more if you can afford to.
The best solution would be to modify the plugin that’s including tabs, etc. to your WordPress site, but that’s not always possible. In some cases, this plugin may be a feasible workaround at least. It will trigger H5P to resize in regular intervals which should let it be displayed in many cases. However, if they appear too frequent, they may cause the browser to stall. Choose the time interval wisely!
If necessary, you can use the manage_h5presizepulse_options capability to control access to the plugin settings.
PLEASE NOTE: H5P IS A REGISTERED TRADEMARK OF JOUBEL. THIS PLUGIN WAS NEITHER CREATED BY JOUBEL NOR IS IT ENDORSED BY THEM.
Install H5P Resize Pulse from the WordPress Plugin directory or upload it manually and activate it. Done. You may want to customize the time interval though.
None so far.
