# Tour of the interface: trees, grids and entity pages

**Goal:** read an entity's last 7 days without opening it, and find the one card you need on a
long edit page — the two ways of browsing your entities and what an entity page offers.
This is one stage of the [Tour of the interface](https://epom.com/ad-server/docs/start/ui-tour.md); the tour needs no data and changes nothing.

## Steps

1. **Trees vs. grids.** Publishers and Advertisers can render as a **tree** (the entity
   hierarchy with expandable levels) or as **grids** (flat tables per level with search,
   sorting, pagination, a column picker and saved views). In tree mode:
   - the keyboard works the way a file tree does — Up/Down between rows, Home/End to the
     first and last row, Right to expand (or step into the first child), Left to collapse
     (or step to the parent), **Enter** or Space to open the entity, and typing letters to
     jump to the next row that starts with them;
   - hovering a row opens a hover card: the entity's name, id and serving state, a 7-day
     sparkline with the figures your role reads in its reports (Viewable impressions,
     Viewable CTR and vCPM on a role on viewable impressions), and quick actions — **Open**, a
     pre-filtered **Analytics** link, **Pause** / **Enable**, and **Copy tag** on placements;
   - the action rail beside the tree holds the create buttons (for example **New advertiser**,
     **New campaign** and **Add new banner for...**; **New site**, **New zone** and
     **Add new placement...**), delete, reload and the hide-inactive toggle;
   - dragging a campaign onto another advertiser, or a banner onto another campaign (zones and
     placements on the Publishers side), opens a copy/move dialog where the hierarchy allows
     it.

   In grid mode the bulk operations — copy, move, link and unlink — go through a floating
   **clipboard bar**: tick rows and click **Add to clipboard**, open the destination level, select
   the target row, then use **Paste a copy**, **Move**, **Link** or **Unlink** on the bar; **Clear**
   empties it.
2. **Entity pages: the Features rail and (i) popovers.** An entity's edit page is a stack of
   cards. On a window at least 1280 px wide, a **Features** rail at the end of the page lists
   the cards that exist for that entity and your role; click one to scroll to it and open it.
   The switch beside a card mirrors the card's own on/off switch, and a lock marks a feature
   you can only view. While the rail is showing, a card whose feature is switched off leaves the
   page — its rail switch turns it back on, and clicking its name brings the card back, collapsed,
   until you switch it on. You can drag the rail's start edge to resize it. A new entity's create
   page has no rail until it is saved. Where a field needs a long explanation, an **(i)** icon sits
   beside its label: hover it, focus it with the keyboard, or tap it to read the text; Enter
   or Space pins it open and Escape closes it.
