Article Introduction：The best way to precisely control the style of drop-down menu elements is to use custom components. 1. Create a container div that contains a drop-down trigger and an option list, and completely control its appearance through CSS; 2. The option style of the native select element is limited and only valid in some browsers; 3. Specific styles can be applied to the target item through the attribute selector, but the cross-browser compatibility is poor. Therefore, when highly customized designs are required, it is recommended to prioritize customization solutions for a more consistent user experience.

Article Introduction：Using data verification in Excel is mainly to limit the data type or range of input in cells and prevent incorrect input. 1. Restrict input to specified options: By setting the source of the list (such as "male, female, unknown"), the drop-down menu selection input is realized; 2. Set the value range: For example, set the age between 18 and 60, select an integer and set the minimum maximum value; 3. Prevent duplicate content: Check uniqueness with the formula = COUNTIF(A:A,A1)=1 to avoid duplication of ID number and other repetitions; 4. Ignore blank items: Check "Ignore empty values", allowing blanks, but the rules must be compliant when filling in, such as 11-digit phone numbers. Using these functions rationally can greatly reduce input errors, especially suitable for multi-person collaboration scenarios.
