Hi Vletm, you're always the one who solves my problems!!

Thank you for your time with me.
I tried, but it doesn't come out the same. If you look in the drop-down menu, I have
Veterinary Visit OK
(space -> perfect)
Lab Tests: (I tried with e.g., but it doesn't come out in bold)
Blood, Exhalation, Gastric Juice, Heces, Orinate, Leche, Others...OK
On-Site Tests: OK... then there should be...
Blood, Exhalation, Gastric Juice, Heces, Orinate, Leche, Others that aren't there.
But maybe I understand why. Because they're called like the ones above, right? Maybe I should add an extra letter.
I don't understand why it doesn't pick up the empty cells to separate the drop-down groups.
In theory, I'd like the drop-down menu to appear like the list in N.
I've always used the drop-down menu, but this time I don't understand why it's so difficult.
