how to show all post in slider.

Post sliders are provided by plugins or are baked into themes. The best way to get an answer to that question is to ask the devs of the particular slider you’re using.

@sterndata thank you,
i am using a premium theme, name jupiter.
an i got few slider plugins with that.
but i am not sure how can i use that so that i can get everything on slider.

@sterndata thank you.
i have asked them, hope they will response me soon.
but i am asking here to know, is it possible to do with wordpress.
if so, then how?
Thanks again

Is it possible? Yes, everything is possible, but it’s not a good idea. Who’s going to slide through all those posts? I think a slider for either featured or more recent posts might work, but more than a few posts is bad UX.

How? Contact your theme developers.
