Hello.You're right.In the settings there is no possibility to change the thickness of the border.You can try to do this with the help of CSS.Give a link to the page of your site and I will try to help.

Mark, is this the page you are referring to?

Esahc, Select the hamburger menu tab and then select current page, you will see on the right hand side the option for border colour, but no option for thickness.

What I want to do is simply add a line at the bottom of the current page to accentuate the page choice.

Thanks Aleksej, but for now, the thickness option should be added by the developers.

"Thanks Aleksej, but for now, the thickness option should be added by the developers." - then wait.

Hi Mark

I've verified the situation and can confirm that even though a border color can be selected, there is no way to display a border for the menu item.

I forwarded the matter to the developers so that the situation can be further examined and will get back to you here as soon as news on this becomes available

Thank you

Stefano
