Mobile & desktop chat settings
ShopGuide keeps device-specific controls short on purpose: separate height limits, and a couple of accommodations for stores with a mobile nav bar or a desktop drawer. On phones, the chat also opens full screen by itself. That's the whole list.
How tall the chat can grow
Set separately per device on the Appearance page, under Chat Max Height: Max height desktop (% of window) and Max height mobile (% of window). Desktop starts at 45% for new stores (35% for stores set up before that change), mobile at 50%. This caps the open chat panel before its message list starts scrolling internally. On phones the limit applies to the inline chat only; once the chat is open full screen, it fills the screen.
Full-screen chat on phones
On phones (screen width up to 749 px), tapping the inline chat (the input, a message or a suggestion chip) or the bubble opens the chat full screen. It has a header with your store name, the cart with its live item count, and a close button, and the input stays pinned above the keyboard. Shoppers close it with the ✕ button, the phone's back gesture or Escape, and the page returns to where it was. If a product comparison table appears, the full screen closes and the page scrolls to the table.
This is on for every store and happens automatically; there is no setting for it in the admin. If you would rather keep the chat inline on phones, contact ShopGuide support.
Cookie banners and consent pop-ups still open on top of the full-screen chat. A cart drawer from your theme with an ordinary stacking order may open behind it after an add to cart; the shopper sees it once they close the chat.
If your theme has a bottom nav bar
Turn on "Store has mobile navigation bar" (Settings → Bubble) and the chat's notification bar shifts up to stay clear of it.
Drawer Mode, desktop only, still experimental
"Enable Drawer Mode (experimental)", under Settings → Experimental Features, opens the chat as a fixed right-side drawer on desktop instead of scrolling the page to it inline. It automatically falls back to the normal behavior below 1024px. Test it thoroughly before trusting it on a live store — it's labeled experimental for a reason.
Not real settings
Don't go looking in the admin app for any of these — they don't exist: hide-on-desktop or hide-on-mobile switches, separate positioning rules per breakpoint beyond the desktop/mobile split above, swipe gestures or drag-and-drop, touch-target sizing controls (tap targets are fixed by the widget's own CSS), or per-device color or font overrides.
Before you call it done
Preview both mobile and desktop in the theme editor after any change. Confirm the bubble and open chat panel don't overlap your theme's own sticky elements — nav bar, sticky add-to-cart, cookie banner. And if you turned on Drawer Mode, resize the browser across the 1024px line to make sure the fallback actually kicks in.
