It is possible to instruct Sift to remember the criteria that have been entered, using the browser's local/session storage function. You can do this by specifying the data-sift-remember-criteria attribute on the Sift outer <div> element. This can be set to session, local or none.
Session storage will apply to the current tab only and the criteria will only be remembered for the lifetime of the tab. If you close the tab or the browser, then the information will be lost. Criteria remembered using session storage will not be available on other tabs, even in the same browser session.
Local storage will apply to all of the browser tabs (except incognito/private tabs) and the criteria will be remembered even if the tab or browser is closed and then re-opened.
You can see and update the information stored in your browser's local/session storage using its developer tools.
