Dynamic content blocks that bring your sidebar (or any area) to life.
Traditional WordPress widgets have been around for years. In the block era, almost all classic widgets have been reimagined as widget blocks. You can use them anywhere – not just sidebars.
In this guide, I’ll cover every widget block:
- Archives
- Calendar
- Categories
- Latest Posts
- Latest Comments
- Search
- Social Icons
- Tag Cloud
- RSS
- Shortcode
By the end, you’ll know how to add dynamic lists, calendars, search forms, and social links – all without touching code.
1. Archives Block – Monthly Post Links
What it does: Displays a list of months, each linking to posts published that month.
When to use: Sidebars on blogs with years of content. Helps readers browse by date.
Settings:
| Setting | Options | Best practice |
|---|---|---|
| Dropdown | Yes / No | Dropdown saves space; list is more visible |
| Post count | Show / Hide | Shows number of posts per month in parentheses |
| Display as | List, Dropdown | List for clarity, dropdown for minimalism |
Pro tip:
Only useful if you have many posts (50+). For newer blogs, skip it.
Shortcut: Type /archives.
2. Calendar Block – Date Navigation
What it does: Shows a monthly calendar grid. Clicking a date shows posts from that day.
When to use: Very niche. Mostly for news sites or daily journals.
Settings:
None. Just add it.
Pro tip:
Most modern sites don’t use calendar – readers prefer search or categories. Use only if your content is time‑sensitive (event blogs, daily deals).
Shortcut: Type /calendar.
3. Categories Block – List of Topics
What it does: Shows all post categories as links. Clicking a category shows all posts in that category.
When to use: Essential for blogs. Helps navigation and SEO (category pages).
Settings:
| Setting | Options | Best practice |
|---|---|---|
| Display as | List, Dropdown | List is clearer for readers |
| Show hierarchy | Yes / No | Shows parent/child indentation |
| Show post count | Yes / No | Number of posts per category |
| Only show top level | Yes / No | Hides sub‑categories |
Pro tip:
- Show post count – signals category activity.
- Use hierarchy if you have sub‑categories (e.g., “WordPress → Gutenberg”).
Shortcut: Type /categories.
4. Latest Posts Block – Recent Articles List
What it does: Displays your most recent blog posts. Highly customizable (show images, excerpts, dates, author, categories).
When to use: Sidebars, homepage sections, footer – anywhere you want to promote fresh content.
Settings:
| Setting | Options | Best practice |
|---|---|---|
| Number of posts | 1–100 | 5–10 is typical |
| Display featured image | Yes / No | Yes – images catch attention |
| Image size | Thumbnail, Medium, Large | Thumbnail (150px) for sidebars |
| Show excerpt | Yes / No | Yes for longer summaries |
| Excerpt length | Words (e.g., 15) | Keep short (10–20 words) |
| Show author | Yes / No | Optional |
| Show date | Yes / No | Usually yes |
| Show categories | Yes / No | Helps readers see topic |
| Order by | Date, Title, Random | Date is default |
| Order | Descending (newest first), Ascending | Descending |
Pro tips:
- Add to footer for site‑wide recent posts.
- Show featured image only if images are consistent (otherwise list only).
- Don’t duplicate – if you already have a Post Grid on homepage, maybe skip this.
Shortcut: Type /latest-posts.
5. Latest Comments Block – Recent Reader Feedback
What it does: Shows the most recent comments left on your site.
When to use: Community‑driven blogs, to highlight engagement. Less common now but can increase interaction.
Settings:
| Setting | Options |
|---|---|
| Number of comments | 1–100 |
| Show avatar | Yes / No |
| Show date | Yes / No |
| Show excerpt | Yes / No (comment text snippet) |
Pro tip:
- Use when you have active commenters – shows social proof.
- Keep number low (5) to avoid clutter.
Shortcut: Type /latest-comments.
6. Search Block – Site Search Form
What it does: Places a search bar on your page. Visitors can type keywords to find content.
When to use: Every site needs a search. Put it in header, sidebar, or footer.
Settings:
| Setting | Options | Best practice |
|---|---|---|
| Button position | Inside (icon), Outside (button text) | Inside saves space |
| Button text | Custom text (e.g., “Search”) | Default “Search” is fine |
| Placeholder | Hint text (“Type and press enter”) | Useful for clarity |
| Label | Show/hide “Search” label | Hide for minimalism |
Pro tip:
- Always include a search block somewhere (usually sidebar, mobile menu, or footer).
- Use wide button for better touch targets on mobile.
Shortcut: Type /search.
7. Social Icons Block – Link to Your Profiles
What it does: Displays clickable icons for your social media profiles (X, Facebook, Instagram, LinkedIn, YouTube, GitHub, etc.).
When to use: Header (top bar), footer, sidebar, contact page – anywhere you want to direct visitors to follow you.
Adding platforms:
- Add Social Icons block
- Click “Add social” and choose platform from dropdown
- Paste your profile URL
- Repeat for each platform
Settings:
| Setting | Options |
|---|---|
| Icon size | Small, Medium, Large |
| Icon color | Use brand colors or custom (recommend brand colors) |
| Background | None, Circle, Square |
| Alignment | Left, center, right |
| Open in new tab | Per link (recommended on) |
Pro tips:
- Don’t add platforms you never post on – dead links hurt trust.
- Use brand colors (blue for X, red for YouTube, etc.) – readers recognize instantly.
- Place in footer and header – both work well.
Shortcut: Type /social-icons.
8. Tag Cloud Block – Popular Keywords
What it does: Displays your post tags in a “cloud” where larger size = more posts with that tag.
When to use: Blogs with many tags. Helps readers find related topics.
Settings:
| Setting | Options |
|---|---|
| Show post count | Yes / No |
| Taxonomy | Tags (default) or Categories |
Pro tip:
- Only useful if you tag consistently – otherwise cloud looks sparse.
- Consider Categories block instead – it’s often cleaner.
Shortcut: Type /tag-cloud.
9. RSS Block – Display Feeds from Other Sites
What it does: Pulls and displays posts from any RSS feed (your other site, a news source, etc.).
When to use: Aggregating content (e.g., “Industry news”), or showing your own posts from a different site.
Settings:
| Setting | Options |
|---|---|
| Feed URL | Paste RSS feed address (e.g., https://example.com/feed) |
| Number of items | 1–20 |
| Show summary | Yes / No |
| Show author | Yes / No |
| Show date | Yes / No |
| Display as | List, Grid |
Pro tip:
- Be careful with copyright – use other sites’ feeds only if allowed.
- Use your own feed to cross‑promote another blog you run.
Shortcut: Type /rss.
10. Shortcode Block – Compatibility with Old Plugins
What it does: Executes any classic WordPress shortcode (e.g., [contact-form-7 id="123"]) inside a block.
When to use: When a plugin still uses shortcodes and doesn’t have a native block.
How to use:
Just paste the shortcode into the Shortcode block.
Settings:
None – the block passes anything inside to the shortcode handler.
Pro tip:
- Try to find a native block version – shortcodes work but blocks are better.
- Use for contact forms, galleries, or sliders from old plugins.
Shortcut: Type /shortcode.

Comparison Table: Which Widget Block Should You Use?
| Block | Best for | Frequency of use |
|---|---|---|

Common Mistakes to Avoid
- Too many widget blocks – clutters sidebar. Pick 3–4 max.
- Missing Search block – every site needs search.
- Outdated social links – remove platforms you abandoned.
- Latest Posts without thumbnails – if your posts have images, show them.
- RSS from low‑quality sources – damages your site’s credibility.
