1 conditional field on multiple groups

Hi Guys
I’m trying to set up State and Cities Dropdowns, this is the code I have
[select* state-from “Texas” “Nevada” “California” “Wisconsin” “Illinois” “NewYork” “Minnesota” “Florida” “Maryland” “Oregon” “Massachusetts” “Georgia”]

[group Nevada][select city-from default:shortcode_attr “Las Vegas” “Henderson” “Reno” “Paradise” “North Las Vegas” “Sunrise Manor” “Spring Valley” “Enterprise” “Sparks” “Carson City” “Other“][/group]

[group California][select city-from default:shortcode_attr “Los Angeles” “San Jose” “San Francisco” “San Diego” “San Jose” “San Francisco” “Fresno” “Sacramento” “Long Beach” “Oakland” “Bakersfield” “Anaheim” “Other“][/group]

[group Wisconsin][select city-from default:shortcode_attr “Appleton” “Green Bay” “Eau Claire” “Kenosha” “Madison” “Milwaukee” “Oshkosh” “Racine” “Janesville” “Rhinelander” “Wausau” “La Crosse” “Marshfield” “Other“][/group]

[group Illinois][select city-from default:shortcode_attr “Chicago” “Aurora” “Joliet” “Naperville” “Rockford” “Springfield” “Elgin” “Peoria” “Champaign” “Waukegan” “Cicero” “Other“][/group]

[group other-city-from]<label style=”color:#535353″> Please specify your State/City </label>[text othercity][/group]

There is a way I can Add show other-city-from when city-from Equal Other Just 1 time and will apply for all the groups?

I hope you Understand
