Remove href params from address bar.

Hi all, I’m using Flask to build my site, currently I have a navbar setup with links to my other pages, here’s one:

<li _class_="nav-item"> <a _class_="nav-link" _href_="{{ _url_for_('pictures',_filename_='templates/pictures.html') }}">Pictures</a> </li>

Now it links fine and works as I want it to, however it also adds the filename after the URL: http://127.0.0.1:5000/pictures?filename=templates/pictures.html. Is there any way to remove the filename, so the address bar simply reads http://127.0.0.1:5000/pictures

Any help would be appreciated.

(I’m self-taught when it comes to HTML and CSS, so forgive any obvious mistakes. if you need any more code, just ask)

Thanks
