Build a custom Vue.js component, implement pull-down multiple selections and support Enter key to add new options. This component combines the convenience of the drop-down menu and the flexibility of free input to enhance the user experience.
Many application scenarios require this feature: you can select multiple values from preset options, and add new options through input and enter. Directly using off-the-shelf UI frameworks such as Element UI or Ant Design is the best way to quickly implement this feature. These frameworks usually offer out-of-the-box components, including pull-down selection, multiple selection, input and enter confirmation, greatly simplifying the development process. Developers only need to configure component properties according to project requirements.
If existing framework components cannot fully meet the needs, secondary development or custom components are required based on the components of these frameworks. This requires a certain amount of experience in Vue.js and component development, involving data binding, event processing, component style and other aspects. Custom component development requires more time and effort, but it can provide more flexible customized solutions.
