I’ve reviewed the latest ABP documentation and samples, but couldn’t find guidance on extending LeptonX UI behavior for accessibility (keyboard interaction and ARIA support).
Context In the LeptonX UI layout, the left navigation menu includes a collapse icon (the small ) that narrows the sidebar to icon-only mode. When collapsed, it automatically expands again when hovered with the mouse.
However, this interaction currently depends entirely on mouse hover, which makes it inaccessible to keyboard and screen reader users. When the menu is collapsed, there’s no keyboard-focusable control available to re-expand it.
What I’m Trying to Achieve
I’d like to implement keyboard accessibility and ARIA support for the LeptonX sidebar collapse/expand toggle, in alignment with WCAG 2.1 AA requirements.
Specifically, the improvements should:
Current HTML Structure
<lpx-icon iconclass="bi bi-filter-left" class="menu-collapse-icon hidden-in-hover-trigger" ng-reflect-icon-class="bi bi-filter-left"> <i aria-hidden="true" class="lpx-icon bi bi-filter-left"></i> </lpx-icon>
Goal Example (Accessible Version)
<button type="button" class="menu-collapse-icon" [attr.aria-label]="isCollapsed ? 'Expand navigation' : 'Collapse navigation'" [attr.aria-expanded]="!isCollapsed" (click)="toggleSidebar()">
Where toggleSidebar() updates the isCollapsed state and toggles a CSS class on the sidebar container.
Request for Assistance Could you please advise on:
Environment Info ABP Framework Version: 9.x UI Framework: Angular (LeptonX Theme) Solution Type: Modular Monolith (ABP Commercial) Browser: Chrome 141 Accessibility Tools Used: NVDA, Axe, and WAVE
Steps to Reproduce
Run the Angular application with LeptonX theme. Collapse the left navigation using the collapse icon. Attempt to re-expand using only the keyboard — there’s no focusable element. Observe: menu can only expand on mouse hover, not via keyboard.
Expected Result
Keyboard users should be able to toggle the sidebar state using Tab + Enter/Space, and assistive technologies should receive correct aria-expanded and label updates.

Hi
How can we get the idle timer to work in the Web Public App?
I added a reference to the Volo.Abp.Account.Pro.Public.Web.Shared 9.2.0 package and added the module dependency. What else do I need to configure?
Thanks Jamie
How do I download the source for this package?
I thought it might be the common commercial source but when I run the get-source, it is not found:
abp-old get-source Volo.Abp.Commercial.Common -o "C:\Users\Jamie\Repo\AbpIO_commercial\modules\Volo.Abp.Commercial.Common" -v 8.3.0

I first noticed this in my own application, then tested the abp demo application to ensure it wasn't a local issue.
The system does not provide any feedback that the password is incorrect.
It appears that this was addressed in the framework by issue 19753 (https://github.com/abpframework/abp/issues/19753).

Hi
I like what you're doing with the lepton-x theme and example components, for example the wizard: https://x.leptontheme.com/side-menu/custom-pages/wizard-horizontal
Are there to develop angular components for these and is the current javascript for the demo pages available?
If there are plans for angular components, can you share a roadmap?
Thanks Jamie
Check the docs before asking a question: https://docs.abp.io/en/commercial/latest/ Check the samples to see the basic tasks: https://docs.abp.io/en/commercial/latest/samples/index The exact solution to your question may have been answered before, and please first use the search on the homepage.

Accessibility tests raises critical issues (using AXE DevTools) for images that do not have alternate text.
A good example of this is the avatar image:

I'm following up on the previously asked question: https://support.abp.io/QA/Questions/4556/Lepton-x-keyboard-support-for-General-Settings
The Lepton-X theme still lacks support for keyboard navigation to the General Settings menu in the MVC project. There have been improvements made to tab navigation to other components, which is great, but it is still not possible to tab to the General Settings and use the enter key to show the options.
This is a high-priority feature for us, as our solution needs to meet accessibility standards. We have developed an accessible theme, but the application fails accessibility checks because users with accessibility requirements can't navigate to the General Settings menu to change to the accessible theme.
Can you provide a technical workaround, is this on your roadmap and what's the estimated release date?
Thanks Jamie
