We have multiple issues on our website with your portfolio.
First of all - when we use the portfolio themplate (with the selector, on the page level) with pagination (we have a lot of items displayed) some of the items are not visible until you switch to page 2 even when you try to select portfolio category. When you switch to page 2 - you automatically loose the entries from page 1.
I suppose the "category" selector should display all entries under the category.
Here is the link to the page https://www.communigator.co.uk/events/
Second thing - because of the issues with pagination we would like to increase the number of items that are displayed in grid - is it possible to increase it from 12 to lets say 24?
Last question - how we can control the order of items that appear in portfolio? for example to group them by name/date etc - this is also not working for us
