pfSense vLAN and UNIFI AP

I have watched this video several times but what I am seeing on the pfsense device I purchased is different. I have purchased the SG-1100 and I cannot assign the vlan to a parent interface. What am I missing with this model of pfsense?

I am doing very similar. Ubiquiti AP > Ubiquiti 16 Port PoE Managed Switch > SG-1100 (pfsense)

Anyone care to enlighten me?

This is what I see when looking at interfaces. The VLAN can only be assigned to the one that is NOT assigned??? parent%20interface|690x289

Hi sir,
Can you show firewall rules? And your Unifi Controller settings?
