Width drop down menu

Site URL: https://www.groei-praktijk.nl/over-lisette-dragt

Dear all,

When navigating in the menu, there is a drop down menu for 3 folders.

For one of those folders (Lisette Dragt) the light grey colour/block in which the text of the drop down is placed is wider than the text itself.

1st picture shows okay drop down: text and box are about equal in width
2nd picture shows not okay drop down: text is far less wide than the width of the drop down menu box

Can someone provide me with CSS code to adjust the width of the drop down menu according to the text that is contained in it?

Thanks a bunch!!

Add to Design > Custom CSS

/* Dropdown auto width */
.header-nav-folder-content {
    width: auto !important;
    min-width: unset !important;
}

Thank you @tuanphan!
