In case if you want to add your own control for selecting a file from external file system in the pop-up window to be linked with the existing “Link” control of every basic block, you can define “externalFilesLibrary” param during plugin initialization as follows:
window.Stripo.init({
...,
externalFilesLibrary: {
buttonText: 'YOUR BUTTON NAME',
open: openLibrary(onFileSelectCallback, onCancelCallback) {
/* Put your logic here.
Call onFileSelectCallback('https://YOUR_STORAGE_FILE_URL') when user select the file from external library. Call onCancelCallback()
when user close the library without file selection. */
}
}
});
Please find a code example here to see how it works.
