What we need to do is we have multiple branch names associated with Team names, so when we click on a branch name in the dropdown, we only want to see the associated team names.
Currently when we click on a branch name all teams are displayed.
We then display the data.
For example, Newcastle branch has the following teams associated: Casualty, Casualty 1, Casualty 2. Birmingham has Casualty Midlands, Casualty Southern. When we click on Birmingham, all of the teams appear, we only want those to appear that are associated with that branch.
