select2-rails

问题 As per title, is there a way to force select2 to always create a dropdown instead of a drop-up? There also appears to be some javascript that is either causing the flip when you scroll above the dropdown, adding a new CSS class "select2-drop-above", or both. EDIT: I should've specified that I'm pulling the library in via select2-rails. I'm hoping there is a way around this that doesn't involve pulling the whole select2 lib in myself and editing the select2.js file directly. 回答1: Modifying the

Here is my setup: apps/assets/application.js $(document).ready(function(){ $(".multiple-input").select2({ theme: "bootstrap"; tags: true; tokenSeparators: [','] }) }); apps

问题 I'm trying to implement select 2 using the select2-rails gem but I'm not familiar with jQuery or rails. I basically tried to copy the placeholder example from this website and adapt it to my needs: http://rails-select2-example.herokuapp.com/ I have a field which lists performers for an event. Originally I just had a simple text field for :performer. But I'd like replace this with a lookup based on my users profile_name which I can then assign to the :performer field. So I have something like

问题 Has anyone come up with a way to limit select2's selection by group? I'm hoping to auto-remove any selection from the same group once something from that group is selected (effectively limiting to one selection per group) I'll be working on something and will post it here if nobody posts a good solution before I'm finished. 回答1: It is possible to prevent selections from being made in Select2, so this can be done depending on how "group" is defined. If a "group" is an <optgroup> in a standard

问题 I have difficulties integrating select2-rails with ActiveAdmin. I followed setup steps on Select2-rails Github page: https://github.com/argerim/select2-rails and I added line: //= require select2 to app/assets/javascripts/application.js and line: *= require select2 to app/assets/stylesheets/application.css so I assume when I have page in ActiveAdmin I should be able to add line: $('#add_student_select').select2() to active_admin.js.coffee But its not working.

问题 The project uses marionette-rails, backbone-on-rails, select2-rails and this port to BackboneForms to provide a multiselect form field. The select options are available to the user. They are retrieved from the collection containing the total list of options: MyApp.module("Products", function(Products, App, Backbone, Marionette, $, _) { Products.CustomFormView = Products.CustomView.extend({ initialize: function(options) { this.model.set("type", "Product"); Products.EntryView.prototype

问题 I cannot see the effect of select2 in rails 5 form whether it's a text_field or select. does anyone know why the tag_list is not being populated.
