css position absolute making the textbox go down

问题

• I build a prototype using chips material-UI.
  • When I click the Test IPA the textbox should show immediately below the text Test IPA.
  • In the prototype, it shows immediately below but whereas when I include with other functionalities, it\'s showing at the bottom.
• I debugged the CSS, its due to position absolute for each scenario it\'s showing different values and its coming from material UI.
• Can you tell me how to fix it with respect to other components?
• Providing my code snippet, sandbox and bug screenshot below.

Working properly individually https://codesandbox.io/s/1y2mvo0ol3

JSX:

<td>
    <ChipsTextbox chipName=\"test IPA\" />
</td>

<Menu id=\"simple-menu\" open={open} onClose={this.handleClose}>
    <TextField onChange={this.onChange} onKeyDown={this.handleKeyPress} />
</Menu>

CSS:

.MuiPopover-paper-1706 {
    outline: none;
    position: absolute;
    min-width: 16px;
    max-width: calc(100% - 32px);
    overflow-y: auto;
    overflow-x: hidden;
    min-height: 16px;
    max-height: calc(100% - 32px);
}

回答1:

The parent element of the .MuiPopover-paper-1706 should have position: relative CSS attribute. If it doesn't then the element with position: absolute will be positioned relatively the nearest parent with relative positioning.
