You're welcome! I'm glad to hear that you were able to solve the problem by adjusting your code. If you have any more questions or need further assistance, feel free to ask.
Hi,
The error you are seeing indicates a problem with the data format being returned from your server.
Based on the code you provided, it looks like you are returning an array of results along with a pagination object in your JSON response. However, Select2 expects the data to be in a specific format, and it's possible that the format of your response is causing this error.
To resolve this issue, you can try formatting your JSON response as follows:
{
"results": [
{"id": "1113042002", "text": "KUTESANGE"},
{"id": "1214012017", "text": "TESIKHORI"},
// Other data...
],
"pagination": {
"more": true
}
}Ensure that the "results" key contains an array of objects where each object has "id" and "text" properties, which are required by Select2. The "pagination" key should indicate whether there are more results available ("more" set to true) or not.
Additionally, you can consider implementing server-side pagination to load a large number of data progressively in smaller chunks, which can improve performance.
If you continue to encounter issues, please provide more details about your Laravel controller and the exact format of the JSON response you are sending to the client.
Thanks
