hyprland-wiki/pages/Configuring/Master-Layout.md

The master layout makes one window be the "master", taking (by default) the left part of the screen, and tiles the rest on the right. You can change the orientation on per-workspace basis if you want to use anything other than the default left/right split.

Quirks

The right, "slave" windows will always be split uniformly. You cannot change their size.

However, you can resize the master window.

Dispatchers

layoutmsg params:

param	description
swapwithmaster	swaps the current window with master. If the current window is the master, swaps it with the first child.
focusmaster	focuses the master window. If the current window is the master, focuses the first child.
cyclenext	focuses the next window respecting the layout
cycleprev	focuses the previous window respecting the layout
swapnext	swaps the focused window with the next window respecting the layout
swapprev	swaps the focused window with the previous window respecting the layout
addmaster	adds a master to the master side. That will be the active window, if it's not a master, or the first non-master window.
removemaster	removes a master from the master side. That will be the active window, if it's a master, or the last master window.
orientationleft	sets the orientation for the current workspace to left (master area left, slave windows to the right, vertically stacked)
orientationright	sets the orientation for the current workspace to right (master area right, slave windows to the left, vertically stacked)
orientationtop	sets the orientation for the current workspace to top (master area top, slave windows to the bottom, horizontally stacked)
