# Blum All-Template Sections

**Theme:** Blum · **Section type:** Overview

All-template sections are sections you can add to any page template, for example a Slideshow on the homepage or a Testimonials section on a product page. Blum also has section groups (Header, Footer, and Overlay) that appear on every page of your store.

> **Note:** Template-based sections, such as Product details or Collection products, belong to one template only. See the article [Template-based section](https://doc.ecomx.co/en/article/template-based-section-obvw19/).

## Understand section groups and template sections
Every page in Blum has 4 areas, from top to bottom:

| Area | What it holds |
| ---- | ---- |
| Header group | The Announcement bar and the Header. Shows on every page. |
| Template | The sections of the page's template, for example the homepage or the product template. Each template has its own sections. |
| Footer group | The Footer. Shows on every page. |
| Overlay group | Popups that open over the page: Newsletter popup, Quick search, and Age verification. Works on every page. |

A change in a section group shows on every page. A change in a template shows on every page that uses that template.

## Add an all-template section
1. In the theme editor, open the template where you want the section, for example **Home page**.
2. In the left sidebar, under **Template**, click **Add section**.
3. Select a section, for example **Image banner**.
4. Set up the section.
5. Click **Save**.

> **Tip:** To add a section to only one product or page, create a new template for it first. See the article [Blum Templates](https://doc.ecomx.co/en/article/blum-templates-57b2vt/).

## Edit the header, footer, and overlay groups
1. In the theme editor, open any page.
2. In the left sidebar, click a section under **Header**, **Footer**, or **Overlay**.
3. Change its settings. To hide a popup, click the eye icon next to it.
4. Click **Save**.

| Group | Sections |
| ---- | ---- |
| Header | Announcement bar, Header |
| Footer | Footer |
| Overlay | Newsletter popup, Quick search, Age verification |

> **Note:** Age verification is added to the Overlay group but hidden by default. Click the eye icon next to it to show it.

## What customers see
- **Header group:** the announcement bar and the header show at the top of every page.
- **Template sections:** the sections of each template show between the header and the footer, in the order you set.
- **Footer group:** the footer shows at the bottom of every page.
- **Overlay group:** popups open over the page, for example the newsletter popup after a delay, or quick search when customers click the search icon.

## Troubleshooting
**I can't add a section to the header or footer.**
Most sections can't be added to the Header or Footer group. Add them to a template instead, right above or below the content you want.

**I added a section to a product page and it shows on every product.**
All products that use the same template share its sections. Create a new product template and assign it to that product.

**I can't find the Popup section.**
The old Popup section is replaced by the **Newsletter popup** in the **Overlay** group. See the article [Blum Popup](https://doc.ecomx.co/en/article/blum-popup-1b6xhi2/).
