Generate an inclusive list featuring li elements with intricately detailed content within each

Currently, I am in the process of developing a web component and here is my code snippet:

        <ul class="list-with-arrow${this.inverse ? '--inverse' : ''}">
        ${this.listData.map((item, index) => {
            return item.link ? html`
                ${index === 0 ? html`<hr class="list-with-arrow__bottom-line${this.inverse ? '--inverse' : ''}" />` : ''}
                <div class="list-with-arrow__container">
                    <a class="list-with-arrow__label-container${this.inverse ? '--inverse' : ''}" href=${item.link} @click=${this.handleItemClick}>  
                        <li data-index="${index}"> 
                            ${item.title ? html`<h5 class="list-with-arrow__title${this.inverse ? '--inverse' : ''}">${item.title}</h5>` : ''}
                            <h4 inverse class="list-with-arrow__label${this.inverse ? '--inverse' : ''}">${item.label}</h4>
                        </li>  
                        <div>
                            <svg width="24" height="24" viewBox="0 0 24 24" fill="none" xmlns="http://www.w3.org/2000/svg">
                                <path fill-rule="evenodd" clip-rule="evenodd" d="M8.99999 4.93933L15.5303 11.4697C15.8232 11.7626 15.8232 12.2374 15.5303 12.5303L8.99999 19.0607L7.93933 18L13.9393 12L7.93933 5.99999L8.99999 4.93933Z" fill="black"/>
                            </svg>
                        </div>
                    </a>
                </div>

I apologize for any confusion as the structure might seem disorganized due to using lit element. The issue arises when testing the component with a screen reader, where it only reads the elements/texts inside without providing information about being in a list or heading out of it. The conventional behavior of a screen reader while navigating through a list is to announce its presence along with the number of items within it, followed by informing when leaving the list.

If you have suggestions on how to make this dynamically bound content inside a list more accessible, please share your insights. Thank you!

Answer №1

It appears that your HTML code is invalid. Only <li> elements can be directly nested within a <ul>.

To resolve this issue, ensure that the first item nested within the <ul> is an <li>. Also, make sure that item.link is wrapped in an <li> tag with content inside it.

Furthermore, there seems to be a second <li> outside of the correct context within the body of the HTML (

<li data-index="${index}">
).

This is also considered invalid as an <li> element must have a parent <ul> or <ol>. It is recommended to replace it with a <div> instead, especially if it serves as a container for heading level 4 or 5 content. You can use CSS for positioning purposes and omit the unnecessary data-index attribute.

The desired output structure should resemble something similar to this (considering the messy nature of the current code and missing information):

<ul class="list-with-arrow">
    <li>
        <hr class="list-with-arrow__bottom-line">
        <div class="list-with-arrow__container">
            <a class="list-with-arrow__label-container href="link"> 
                <div data-index="1"> 
                    <h5 class="list-with-arrow__title">Title</h5>
                </div>  
                <div>
                    <svg focusable="false" aria-hidden="true" width="24" height="24" viewBox="0 0 24 24" fill="none" xmlns="http://www.w3.org/2000/svg">
                        <path fill-rule="evenodd" clip-rule="evenodd" d="M8.99999 4.93933L15.5303 11.4697C15.8232 11.7626 15.8232 12.2374 15.5303 12.5303L8.99999 19.0607L7.93933 18L13.9393 12L7.93933 5.99999L8.99999 4.93933Z" fill="black"/>
                    </svg>
                </div>
            </a>
        </div>
    </li>
[...further items]
</ul>

I have included some recommendations on how to handle the SVG for accessibility, depending on whether it contains essential information or not for screen readers.
