I have attached a patch to disable this. The swap over happens when the number of items gets sufficiently large and a jQuery-based widget called select2 replaces all select boxes in Galaxy - unless explicitly disabled. I understand the desire to disable this. I am not sure anyone is really very pleased with select2 for multiple select widgets - it might be worth just disabling it for multiple select form elements all together globally. I don't know. -John On Thu, Jan 23, 2014 at 4:23 AM, Johannes Eichner <johannes.eichner@uni-tuebingen.de> wrote:

Dear Galaxy Dev-Team,

when using the select parameter in conjunction with options loaded from a text file in the tool_data_path directory (e.g., <options from_file=available_options.txt>) and with the "multiple" attribute set to true, I found that the form of the corresponding HTML widget displayed in the webinterface depends on the number of options listed in the text file. Is there a way to avoid this behaviour in the sense that a fixed HTML form is used independent of the number of available options? It would be great if this was possible, for instance, by changing the value of the display attribute of the select parameter. However, I would also be glad if you could just tell me, where this behaviour of Galaxy is implemented in the source code, such that I can change it according to my needs.

Kind regards, Johannes
