Elegantly handle button overflow: Dynamic adjustment of width with "More" button function

In UI design, the number of buttons and text length are often difficult to predict. How to solve this problem gracefully when a line can only accommodate a limited number of buttons (such as four) and the button text is too long and the display is incomplete? This article provides a solution to dynamically adjust the button width while displaying up to four buttons and integrate the excess into the "More" button.

The core lies in flexible handling of button width and layout. Flex layout is an ideal solution, which enables button wrapping and width adaptation.

First, set the button style: width: max-content; allow the button width to adapt to the content; max-width: [第一行最大宽度]; limit the maximum width of the button to prevent a single button from occupying too much space. "First row Maximum Width" can be calculated dynamically based on the screen width to prevent the button from exceeding the screen.

Secondly, the button container style is crucial: set the container height to a line of button height, and use overflow: hidden; hide overflow buttons; flex-wrap: wrap; allow buttons to wrap automatically. In this way, when the button text is too long, it will occupy the available space as much as possible until the maximum width is reached; if the excess part is automatically wrapped, hiding the overflow content, so that only the first few buttons are displayed.

Finally, implement the "More" button function. After clicking the "More" button, you need to determine the position of each button and fully display all buttons in the new interface. This requires getting the width and position information of each button, dynamically computing and rendering all buttons. This part requires JavaScript code to implement specific logic and dynamically build a new interface based on button position information.

Through reasonable Flex layout and CSS style, combined with JavaScript's dynamic processing, a flexible and user-friendly button component can be created to effectively solve button overflow problems.
