Using JavaScript and PHP to create a Button -

I am trying to create a button after a list. It is to see that the selection has been done and then there is a need to examine the preparation of a new list based on the selection

 `Select a horse:" $ table_header_horse_type; $ array_of_horses = ["horse_type = "" Horse type "]; $ user_horse_type_options = array (" mh_maintenance "=>" mature horse, maintenance "," mh_mare_late_gest "=>" mare - late pregnancy period "," mh_mare_early_lac "=>" mare - early milk " , "Mh_mare_late_lact" => "mare - late milk", "w_light" => "work, light", "w_mod" => "work, medium", "w_heavy" => "work, intense", "yh_nurse_foal" = > "Nursing Colt, 3 Months", "yh_wean_foal "Yah_long_year" => "long salting, 18 months", "yh_two_yrs" => "two years old, 24" "milk colt, 6 months", "yh_year_foal" => "shock of the year, 12 months" Month "); // Array for horse type - the user has selected a $ selector_horse_type = ''; {$ selector_horse_type foreach ($ unique_name => $ user_horse_type_options as $ human_readable =) = '' $ human_readable '' '..} $ Selector_horse_type. = ""; Echo $ selector_horse_type; // list picker displayed page`

A good way is doing this with javascript. If the selection is done you are not making the button, but the selection was made after you will be displayed button. There is a good javascript plugin that is highly used Jquery UI will use the show () function: Here is a link if you add your code to this question, we can help further.
