show the li that has an anchor link which has a data attribute name "data-link" that match unto specified text

Base from my snippets below, firstly, If i clicked unto any branch from a dropdown that has a label of "select branch", then it will get the text from a clicked branch (anchor link e.g. Iligan) and then hide all the li's from the ul of a dropdown that has a label of "select user" and then show all li's that has a link with a data attribute named "data-link" and its content match on the text of the select branch dropdown currently clicked link but sadly not working, I can hide all li's but unable to show those li that has an anchor link with a data attribute named "data-link" which data-link content is matched to the text of the currently clicked link from the select branch dropdown. Any help, suggestions, clues, recommendations, ideas would be greatly appreciated. Thank you!
