It depends what you want to use the bridge for.
If you just want a loopback interface you can create the bridge without any ports assigned to it, you'll just assign the bridge an IP address.
For a normal setup where the router provides DHCP for all the LAN ports (except the port connected to the WAN/Internet) and wireless interface, you'll create a bridge then assign your LAN ports and wireless interface(s) to the bridge.
By default the MikroTik router will bridge all the LAN ports.
