multi-select

问题 The current implementation for multi-select doesn't show <mat-select [formControl]="toppings" multiple> because here for type 'array' and 'enum' it shows 'checkboxes'.

问题 I'm attempting to connect a datatable with a multiselect widget in bokeh. I've searched around and gathered that I need to develop a function to update the data source for the data table, but I seem to have two problems. I cannot seem to access the value of the multiselect object after I click it. I cannot seem to push the change to the notebook after receiving the change. Here's an example of my code: import pandas as pd from bokeh.io import push_notebook from bokeh.plotting import show,

问题 I'm currently using the Chosen jQuery plugin. Check out my fiddle here: http://jsfiddle.net/3XWSe/ Try the fiddle in both Chrome and Internet Explorer (I tested using IE version 11). Notice there is a delay (4 or 5 seconds) when clicking on the multiselect in Internet Explorer, as compared to very little, almost none, in Chrome. This example dropdown is listing all the cities in Texas and has close to 5000 options. I opened up chosen.jquery.js and traced the problem to this call: Chosen

问题 I have followed this answer How to add more custom field in Linked Product of Woocommerce to add a custom select field to my Linked Product screen in Woocommerce. This new field is meta key is subscription_toggle_product . It's working fine, but once you have selected a product, you can't delete it (there is no "Empty" option or cross symbol).

问题 This is a very short question: Recently Google has updated its material design guidelines, showing that multi selection of items should be like on the Google-Photos app (here), as such: I've noticed that even if you are already in multi-selection mode, you can still use this gesture anywhere you wish. What I did so far is handling clicking of items for multi-selecting them, but how do I do what Google has shown? 回答1: Although it's complicated and there are some libraries to use, it will be

问题 I'm using the excellent jEditable plugin for some in-place editing on my page. There is one spot I need a multiple select element. Is there a jEditable plugin that allows me to do this? I've been trying to use the jEditable author's plugin API to create my own multiselect plugin, but no dice so far. There just doesn't seem to be quite enough documentation on what each function does in the API. And every single example plugin he provides appears to rely on other jQuery plugins. I just need a

问题 I adopted the code from this post and made this fiddle. Try clicking the first row, then shift-clicking the last row. If you notice this code does very well, except the last row, the row that you click on, does not get selected. I have been scratching my head on this one.
