Alter Exposed filter form

I would like to know how to get parent terms only, for example “Ages 0-2” and also print in dropdown.

This is the structure of the form array.

Array(   [#info] => Array(     [filter-tid] => Array(       [operator] => tid_op       [value] => tid       [label] => Term       [description] =>      )   )   [tid] => Array(     [#type] => select     [#options] => Array(       [All] => - Any -       [0] => stdClass Object(         [option] => Array(           [367] => Ages 0-2         )       )       [1] => stdClass Object(         [option] => Array(           [2378] => -Infant         )       )     )   ) )

This is the code I am using.

  if ($form['#id']== "views-exposed-form-quick-find") {      $test = $form['tid']['#options'];     foreach ($test as $tid) {       // It prints "Array" and the "Trying to get property of non-object" message.       print $tid->option;     }   }

I do not understand why the “Array” text repeats; it could be I am not pointing to right array.

How do I remove all children which do not have “age 12 – 14” (see “-” in the middle not from start)?
