How to create dependent dropdown lists in Excel
Article Introduction：The key to creating a dependency drop-down list in Excel is to understand the use of data structures and functions. There are three main methods. 1. First organize the basic data source, such as the classification and corresponding subitems are listed separately, and it is recommended to use naming scope management; 2. Use the "Data Verification" "INDIRECT" function to achieve linkage, provided that the main pull-down option is consistent with the named area name; 3. Use the FILTER function (suitable for Excel365 or 2021 and above), and achieve more flexible linkage through dynamic filtering. The formula is =UNIQUE (FILTER (sub-item column, classification column =main pull-down cell)). Pay attention to naming specifications, tidy data and function limitations to ensure smooth secondary linkage effect.

Manage the 'Select All/No Select All' checkbox functionality in a standalone container using jQuery
Article Introduction：This article introduces in detail how to use jQuery to implement the "Select All/No Select All" function of multiple sets of check boxes to ensure that each set of check boxes is operated in an independent HTML container without affecting each other. By adding specific class names to the parent container and the "Select All" check box, combined with jQuery's event listening, DOM traversal and property operations, we can control the selected status of all check boxes in the same group when clicking "Select All" and reverse linkage, that is, when all check boxes in the same group are automatically selected, or when any check box is unchecked, "Select All" is automatically cancelled.
